# 142.86 minutes in hours

## Result

142.86 minutes equals 2.381 hours

You can also convert 142.86 minutes to hours and minutes.

## Conversion formula

Multiply the amount of minutes by the conversion factor to get the result in hours:

142.86 min × 0.0166667 = 2.381 hr

## How to convert 142.86 minutes to hours?

The conversion factor from minutes to hours is 0.0166667, which means that 1 minutes is equal to 0.0166667 hours:

1 min = 0.0166667 hr

To convert 142.86 minutes into hours we have to multiply 142.86 by the conversion factor in order to get the amount from minutes to hours. We can also form a proportion to calculate the result:

1 min → 0.0166667 hr

142.86 min → T(hr)

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

T(hr) = 142.86 min × 0.0166667 hr

T(hr) = 2.381 hr

The final result is:

142.86 min → 2.381 hr

We conclude that 142.86 minutes is equivalent to 2.381 hours:

142.86 minutes = 2.381 hours

## Result approximation

## Units definitions

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

### Minutes

The minute is a unit of time or of angle. As a unit of time, the minute (symbol: min) is equal to 1⁄60 (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions 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 unit of angle, the minute of arc is equal to 1⁄60 of a degree, or 60 seconds (of arc). Although not an SI unit for either time or angle, the minute is accepted for use with SI units for both. The SI symbols for minute or minutes are min for time measurement, and the prime symbol after a number, e.g. 5′, for angle measurement. The prime is also sometimes used informally to denote minutes of time. In contrast to the hour, the minute (and the second) does not have a clear historical background. What is traceable only is that it started being recorded in the Middle Ages due to the ability of construction of "precision" timepieces (mechanical and water clocks). However, no consistent records of the origin for the division as 1⁄60 part of the hour (and the second 1⁄60 of the minute) have ever been found, despite many speculations.

### Hours

An hour (symbol: h; also abbreviated hr.) is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions. The seasonal, temporal, or unequal hour was established in the ancient Near East as 1⁄12 of the night or daytime. Such hours varied by season, latitude, and weather. It was subsequently divided into 60 minutes, each of 60 seconds. Its East Asian equivalent 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 eventually 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. This was finally abandoned due to the minor slowing caused by the Earth's tidal deceleration by the Moon. In the modern metric system, hours are an accepted unit of time equal to 3,600 seconds but an hour of Coordinated Universal Time (UTC) may incorporate a positive or negative leap second, making it last 3,599 or 3,601 seconds, in order to keep it within 0.9 seconds of universal time, which is based on measurements of the mean solar day at 0° longitude.
