How many seconds in 640 minutes?

Conversion formula

The conversion factor from minutes to seconds is 60, which means that 1 minute is equal to 60 seconds:

1 min = 60 s

To convert 640 minutes into seconds we have to multiply 640 by the conversion factor in order to get the time amount from minutes to seconds. We can also form a simple proportion to calculate the result:

1 min → 60 s

640 min → T_(s)

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

T_(s) = 640 min × 60 s

T_(s) = 38400 s

The final result is:

640 min → 38400 s

We conclude that 640 minutes is equivalent to 38400 seconds:

640 minutes = 38400 seconds

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 2.6041666666667E-5 × 640 minutes.

Another way is saying that 640 minutes is equal to 1 ÷ 2.6041666666667E-5 seconds.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred forty minutes is approximately thirty-eight thousand four hundred seconds:

640 min ≅ 38400 s

An alternative is also that one second is approximately zero times six hundred forty minutes.

Conversion units

The units involved in this conversion are minutes and seconds. 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.

Second

The second (symbol: s) (abbreviated s or sec) is the base unit of time in the International System of Units (SI). It is qualitatively defined as the second division of the hour by sixty, the first division by sixty being the minute. The SI definition of second is "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom". Seconds may be measured using a mechanical, electrical or an atomic clock. SI prefixes are combined with the word second to denote subdivisions of the second, e.g., the millisecond (one thousandth of a second), the microsecond (one millionth of a second), and the nanosecond (one billionth of a second). Though SI prefixes may also be used to form multiples of the second such as kilosecond (one thousand seconds), such units are rarely used in practice. The more common larger non-SI units of time are not formed by powers of ten; instead, the second is multiplied by 60 to form a minute, which is multiplied by 60 to form an hour, which is multiplied by 24 to form a day. The second is also the base unit of time in other systems of measurement: the centimetre–gram–second, metre–kilogram–second, metre–tonne–second, and foot–pound–second systems of units.
