Conversion formula exactly how to convert 120 minute to hours?

We understand (by definition) that:1⁢min≈0.016666667⁢hr

We can collection up a proportion to fix for the variety of hours.

You are watching: 120 minutes is how many hours

1⁢min120⁢min≈0.016666667⁢hrx⁢hr

Now, we cross multiply to solve for our unknown x:

x⁢hr≈120⁢min1⁢min*0.016666667⁢hr→x⁢hr≈2.0000000399999998⁢hr

Conclusion:120⁢min≈2.0000000399999998⁢hr

Conversion in the contrary direction

The train station of the conversion aspect is that 1 hour is equal to 0.5 time 120 minutes.

It can also be expressed as: 120 minutes is same to 1 0.5 hours.

Approximation

An almost right numerical result would be: one hundred and twenty minutes is about zero hours, or alternatively, a hour is around zero time one hundred and also twenty minutes.

Units involved

This is exactly how the units in this conversion are defined:

Minutes

"The minute is a unit of time or the angle. Together a unit of time, the minute is same to 1⁄60 (the first sexagesimal fraction) of one hour, or 60 seconds. In the UTC time standard, a minute on rarely occasions has actually 61 seconds, a repercussion of leap seconds (there is a provision to insert a an adverse leap second, i beg your pardon would result in a 59-second minute, however this has never occurred in more than 40 years under this system). As a unit that angle, the minute of arc is equal to 1⁄60 the a degree, or 60 secs (of arc). Although not an SI unit for either time or angle, the minute is embraced for use v SI devices for both. The SI symbols for minute or minutes room min for time measurement."

Hours

"Midnight (or noon) ~ above a 12-hour analog clock one hour is a unit of time conventionally reckoned as 1⁄24 that a day and also scientifically reckoned together 3,599–3,601 seconds, depending on conditions.The seasonal, temporal, or unlike hour was created in the ancient Near eastern as 1⁄12 that the night or daytime. Such hours varied through season, latitude, and also weather. It was subsequently separated into 60 minutes, every of 60 seconds. That East oriental equivalent was the shi, which was 1⁄12 the the apparent solar day; a comparable system to be eventually arisen in Europe i beg your pardon measured its equal or equinoctial hour together 1⁄24 of together days measured indigenous noon to noon. The boy variations that this unit were eventually smoothed by making it 1⁄24 of the median solar day, based on the measure of the suns transit along the celestial equator fairly than follow me the ecliptic. This was lastly abandoned as result of the young slowing caused by the Earths tidal deceleration through the Moon.In the modern-day metric system, hours are an accepted unit that time same to 3,600 seconds but an hour of Coordinated global Time (UTC) might incorporate a hopeful or an adverse leap second, making it last 3,599 or 3,601 seconds, in stimulate to save it in ~ 0.9 secs of universal time, i m sorry is based on measurements that the average solar day at 0° longitude."
