Hours in 90 Minutes

Because one hour equals sixty minutes, to convert 90 minutes to hours, you have to divide the number of minutes, 90, by 60.

The 90 minutes into Hours formula is:

h = 90 min / 60

90 min = 1.5 h (decimal, curved to 5 places).

Next, we show you how to alter the amount of time to hours and minutes combined.

90 Minutes to Hours and Minutes

Ninety minutes = 1 hour and 30 minutes.

This alternative conversion is way more shared in daily life!

The non-decimal conversion formula goes as follows:

INT(90/60) hours + MOD(90,60) minutes

To obtain this result proceed as follows:

Obtain the whole number part of division 90 / 60, INT(90/60), and write it down as hrs: 1.

Calculate the remainder of the preceding division as 90 – (1 × 60), and write it down as min: 30.

Proof: (1 × 60) + 30 = 90.

What is the inverse Calculation between 1 Hour and 90 Minutes?

Performing the inverse calculation of the relationship between units, we obtain that 1 hour is 0.66666667 times 90 minutes.

Change Plan

The conversion issue from minutes to hours is 0.016666666666667, which means that 1 minute is equal to 0.016666666666667 hours:

1 min = 0.016666666666667 hr

1 min → 0.016666666666667 hr

Ninety min → T(hr)

Solve the above proportion to get the time T in hours:

T(hr) = ninety min × 0.016666666666667 hr

T(hr) = 1.5 hr

The final result is:

Ninety min → 1.5 hr

We conclude that minutes Ninety is equal to 1.5 hours:

How long is 90 minutes = 1.5 hours

Alternative Conversion

Conversion Units

The units involved in this change are minutes and hours. This is how they are defined:


A minute is a unit of time or angle. The minute (symbol: min) equals 1⁄60 (the first sexagesimal fraction) of an hour or 60 seconds as a time component. In the UTC standard, a minute on rare times has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). As a viewpoint unit, the minute arc equals 1⁄60 of a grade, or 60 seconds (of the turn). Though not an SI unit for either time or angle, the minute is putative for use with SI units for both. The SI cyphers for minute or minutes are min for time size, and the prime symbol after a number, e.g. 5′, for angle measurement.


An hour (symbol: h; also abbreviated hr.) is a unit of time conventionally calculated as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, contingent on situations. The seasonal, temporal, or unsatisfactory hour was established as 1⁄12 of the night or daytime in the ancient Near East. Such hours varied by season, leeway, and weather. It was subsequently alienated into 60 minutes, each of 60 seconds. The East Asian equal was the shi, which was 1⁄12 of the apparent solar day; a similar system was eventually developed in Europe, which measured its equal or equinoctial hour as 1⁄24 of such days measured from noon to noon. The minor variations of this unit were finally smoothed by making it 1⁄24 of the mean solar day, based on the measure of the sun’s transit along the celestial equator rather than along the ecliptic.
