Even if the topic of kilowatts no something you think about every day, it’s certainly something the affects your daily life. You see, a watt is the simple unit of measurement offered for electric power. The ax “watt” comes from James Watt the Scotland, one engineer, entrepreneur, craftsman, instrument maker, and also scientist who is often referred to together the father of the industrial Revolution. One of his many notable achievements was around 1775, as soon as he created the Watt heavy steam engine. Today, vapor turbines in ~ thermal power plants use this same technology to convert thermal power into mechanically energy. We measure that electrical power in kilowatts.
In this guide, we take the facility subject that kilowatts and simplify it into more relatable terms. Here, you’ll gain a better understanding the what kilowatts are, plus we’ll covering things like what we measure in kilowatts, how we convert and calculate kilowatts, and also how kilowatts different from kilowatt-hours, megawatts, and also gigawatts.
What Is a Watt? What Is a Kilowatt?
Before we discuss kilowatts, let’s take a second to talk about watts (W). Watts space the straightforward unit the power supplied to measure electric, thermal, and mechanical power. One watt is equal to one joule, and one volt-ampere. Every one of these terms measure electrical power.
Now, let’s acquire into a much more detailed summary of what a kilowatt (kW) is. Many simply, a kilowatt is another term offered in the measure of power. Many frequently, we use kilowatts to measure up residential and commercial power.
Keep in mind the the prefix “kilo” way one thousand. It may be much easier for you to remember the one kilowatt equates to 1,000 watts of electric power once thinking the the prefix’s meaning. Because that example, a microwave v a 1,000-watt label requires 1,000 watts worth of power (or 1 kW) come work.
How do You transform Watts into Kilowatts? just how Do You transform Kilowatts to Watts?
The counter of watts to kilowatts is simply as straight-forward together you may have guessed. We uncover the strength in kilowatts P(kW) by dividing the power in watts P(W) by 1,000.
Here’s the Formula because that Converting Watts into Kilowatts:P(kW) = P(W) / 1,000
For example, if you wanted to convert your 1500W dishwasher come kilowatts, you would carry out the adhering to calculation:P(kW) = 1,500W / 1,000 = 1.5kW
Here’s another way to think of the that might make the math easier. Include a decimal point at the end of your whole number. In this case, it’s 1500. Then, due to the fact that there room three zeros in 1,000, i beg your pardon is the number you’re dividing by, friend will relocate the decimal allude three digits, or three spaces, come the left. You finish up with 1.500, or 1.5. This trick provides it really straightforward to convert watts right into kilowatts v some fast mental math.
Here’s the Formula because that Converting Kilowatts into Watts:
Since we recognize that one kilowatt is equivalent to 1000 watts, we reverse the operations above to solve this equation.1kW = 1000W P(W) = 1000 × P(kW)
For example, if you recognize that your dishwasher provides 1.5kW, friend would carry out the equation below to discover that your dishwasher is a 1500W appliance or calls for 1500W of power to work.Convert 1.5kW to watts: P(W) = 1000 × 1.5kW = 1500W
How numerous Kilowatts room in a Megawatt?
We usage megawatts once measuring power on a much bigger scale. If you wanted to know just how much power is produced by a power plant or just how much electrical power is forced to power an entire city, girlfriend would use megawatts. Because that example, a usual coal strength plant is about 600 MW in size.
To proceed along the course of maintaining things simple, usage the same formula used above to convert kilowatts to megawatts (MW). Why is that? Well, since 1,000 kilowatts space equal come — girlfriend guessed that — one megawatt.
Here’s the Formula to transform Kilowatts come Megawatts:P(MW) = P(kW) / 1,000
This formula also method that if girlfriend would prefer to transform watts to megawatts, you have to add three more zeros to your equation. The power in megawatts P(MW) have the right to be found by separating the power in watt P(W) by 1,000,000.
Here’s the Formula to transform Watts come Megawatts:P(MW) = P(W) / 1,000,000
For example, if you transform a 100-watt light bulb to megawatts, girlfriend will execute the complying with calculation:P(MW) = 100W / 1,000,000 = 0.000100MW
How plenty of Megawatts are in a Gigawatt?
Suppose you’re searching for an also larger measure up unit. In that case, you’ll want to usage gigawatts, which we usage to measure exactly how much power large power plants or numerous plants deserve to generate together. In 2012, the complete capacity of unified States electrical energy generating plants was about 1,100 GW.
You’ve most likely noticed a pattern creating here. In that case, you may have a great idea regarding what the formula is because that converting megawatts to gigawatts (GW). If girlfriend guessed the there space 1,000 megawatts in one gigawatt, you would be correct. That fun fact means that there room 1,000,000 kilowatts in one gigawatt and 1,000,000,000 watts in one gigawatt. Whew!
What space Kilowatt-Hours? are Kilowatt-Hours different Than Kilowatts?
Now, here’s where things can gain a little bit confusing. A kilowatt-hour (kWh) is a measurement of just how much power is used. However, this is not actually the same as measuring the variety of kilowatts you usage per hour because power and energy space not the same. Instead, a kilowatt-hour actions the quantity of time, or the lot of energy, that takes to use one kilowatt the power.
The lot of energy used if a 1,000-watt appliance runs because that one hour is same to one kilowatt-hour. The reduced the wattage an object has, the better.
Here’s an example: If you were to usage a 100-watt irradiate bulb, it would certainly wield one kilowatt-hour of energy after 10 hrs of use. But, if you switched to a an ext energy-efficient light bulb that just requires 40-watts to develop the very same amount that light, it will take 25 hours to usage one kWh of energy. Imagine the energy savings you could attain by switching out all of the lightbulbs in your home.
Just favor measuring strength consumption, once you calculation the amount of power used or produced on a larger scale, friend would use megawatt-hours (MWh) or gigawatt-hours (GWh).
How carry out I calculation the Energy usage of an electrical Appliance?
How Is My energy Use in Kilowatt-Hours Calculated?
Much prefer one kilowatt is same to 1,000-watts the power, one kilowatt-hour is tantamount to 1,000-watts, or joules, of power use end one hour. If you want to convert watts into kilowatt-hours to find out exactly how much energy your coffee device consumes every day, you would multiply the power intake in watts by the number of hours used. Then, division that number through 1,000.
Here’s the Formula for Calculating Watts right into Kilowatt-Hours:kWh = (watts × hrs) ÷ 1,000
For example, to find the kWh the 1,200 watts for 3 hours:kWh = (1,200 × 3) ÷ 1,000 kWh = 3,600 ÷ 1,000 kWh = 3.6
How carry out I convert My Energy intake of Kilowatt-Hours into Watts?
Suppose you to be interested in law the turning back to determine how many watts her coffee device is, based on its kilowatt-hours. In that case, you can easily execute so by making a couple of simple adjustments come the formula.
For this conversion, multiply the energy used in kWh by 1,000 to find the energy intake in watt-hours. Then, you must divide the number by the number of hours you provided it.
Here’s the Formula for Calculating Kilowatt-Hours into Watts:watts = (kWh × 1,000) ÷ hrs
For example: let’s find the watts of power for 3.6 kWh of power used in 3 hours.watts = (3.6 kWh × 1,000) ÷ 3 hrs watts = 3,600 ÷ 3 hrs watts = 1200 W
What go One Kilowatt-Hour of electric Energy Cost?
Most utility providers calculate your electrical power bill based upon how countless kilowatt-hours, or units of energy you use each month. Since the clinical unit of energy is measure up in joules, you will regularly see your energy usage detailed in joules ~ above your electric bill. Remember, one joule is same to one watt. If girlfriend can transform watts to kWh, you can predict exactly how much it might expense to run your various electrical appliances and devices.
In 2020, Idaho occupants paid the shortest average electricity rates in the U.S. In ~ 9.67 cent per kWh. In excessive contrast, citizens in Hawaii payment the most, through their average 2020 power rates coming in roughly 28.84 cents per kWh.
How carry out I calculation the usage of an electric Appliance? how Do I estimate What My electricity Bill will certainly Be?
Let’s usage the national median rate of roughly 13 cents per kWh come calculate how much it expenses to power a 100-watt light bulb every hour. Since it takes 100 watts of strength to work-related — to convert the strength in watt to kilowatt-hours — you will certainly multiply 100 watt by one hour. Then, you’ll divide by 1,000 to find the energy consumption in kWh.Energy = (100 × 1) ÷ 1,000 Energy = 100 ÷ 1,000 energy = 0.1 kWh Hourly cost = electricity price per kWh ÷ power use in kWh Hourly expense = $0.13 ÷ 0.1 kWh Hourly cost = 1.3 cents
If electricity expenses 13 cents per kWh, then a 100-watt light bulb will expense 1.3 cent for every hour that it’s on. Most electrical bills room calculated monthly. To calculation your monthly costs, you can follow these steps:Estimate how countless hours per day you usage that light bulb on average. (Let’s say it’s 5 hours).
Multiply the light bulb’s watts by the average variety of hours you usage it everyday instead that the one hour provided in the formula above. (Let’s say your light bulb is 60 watts, so the you would calculate 60 watts x 5 hours).Solve the equation above using her light bulb’s actual wattage and also the really average variety of hours you usage that light pear per day. (60 x 5 = 300 ÷ 1,000 = 0.3 kWh). Multiply her answer by 30 to gain the monthly mean kWh for that light bulb. In this case, $0.43 x 30 work = $3.90. The would cost you $3.90 every month to leaving a 60-watt light bulb on because that an average of 5 hrs per day, every day. Repeat this equation for all light bulbs, appliances, and also other electrical gadgets in your home. Add up the total to find your approximated monthly electricity costs in kilowatt-hours. You may be surprised to view how fast it all adds up.
How countless Kilowatt-Hours go the mean U.S. Family members Use every Day?
Now that you understand all around how to calculate the kWh that energy usage you use, it could be exciting to to compare your power use to others in the joined States. The average house in the U.S. Consumed 887 kilowatt-hours (kWh) of electrical energy per month in 2019, which breaks down to almost 30 kWh every day. If you’re curious to watch where girlfriend stand contrasted to others in your specific region or state, examine out this data noted by the U.S. Power information administration.
How many Kilowatts need to a Generator be to operation a House?
If you live in an area prone to weather the could an outcome in strength outages, friend can give yourself a small peace of mind by investing in a generator. Freezers, lights, refrigerators, and well pumps are simply a few of the appliances you could keep running during a strength outage.
The most vital household tools can be run v a 5,000 come 7,500 watt rated generator. If girlfriend would like your whole house to continue operating, you will likely need to go larger. If you have actually fewer appliances, you may be able to get away through something smaller. Determining the wattage of your essential appliances will help you figure out what dimension generator you will need.
What’s the Difference in between Watts and also Amps?
Watts and also amperes, additionally known as amps, room both units used to measure electrical power intake or production. Every electronic tools have their power consumption listed on their label in either watts or amps. If the label on your maker lists amps, you can calculate the wattage by using a basic formula.
Here’s the Formula for Calculating Amps come Watts:
Wattage = Amps x 120
For example, if you have actually a 120V machine with a 20 amp label, that’s indistinguishable to a wattage that 2400. In equation form, that is: 20A x 120V = 2400W
What Is the Kilowatt-Peak?
Kilowatt-peak (kWp) refers to the rate a system can generate energy during its peak performance, i beg your pardon is when it’s functioning at its preferably capacity. We most commonly use kWp for solar electrical energy systems. These systems room labeled with a rating in kilowatts optimal (kWp) so that consumers deserve to compare the output capabilities and also size of assorted photovoltaic panels.
A 2 kWp mechanism will create 2 kW of electrical power only during the brightest sunshine when all problems are at their best. Standard modules take roughly 6.25 square meter of roof an are for each kWp. Higher efficiency modules usage only 5 square meters of roof space.
