How many hours in 1989 minutes?

Conversion formula

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

1 min = 0.016666666666667 hr

To convert 1989 minutes into hours we have to multiply 1989 by the conversion factor in order to get the time amount from minutes to hours. We can also form a simple proportion to calculate the result:

1 min → 0.016666666666667 hr

1989 min → T_(hr)

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

T_(hr) = 1989 min × 0.016666666666667 hr

T_(hr) = 33.15 hr

The final result is:

1989 min → 33.15 hr

We conclude that 1989 minutes is equivalent to 33.15 hours:

1989 minutes = 33.15 hours

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 hour is equal to 0.030165912518854 × 1989 minutes.

Another way is saying that 1989 minutes is equal to 1 ÷ 0.030165912518854 hours.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one thousand nine hundred eighty-nine minutes is approximately thirty-three point one five hours:

1989 min ≅ 33.15 hr

An alternative is also that one hour is approximately zero point zero three times one thousand nine hundred eighty-nine minutes.

Conversion units

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

Minute

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.

Hour

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.
