How many minutes in 308.5 seconds?

Conversion formula

The conversion factor from seconds to minutes is 0.016666666666667, which means that 1 second is equal to 0.016666666666667 minutes:

1 s = 0.016666666666667 min

To convert 308.5 seconds into minutes we have to multiply 308.5 by the conversion factor in order to get the time amount from seconds to minutes. We can also form a simple proportion to calculate the result:

1 s → 0.016666666666667 min

308.5 s → T_(min)

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

T_(min) = 308.5 s × 0.016666666666667 min

T_(min) = 5.1416666666667 min

The final result is:

308.5 s → 5.1416666666667 min

We conclude that 308.5 seconds is equivalent to 5.1416666666667 minutes:

308.5 seconds = 5.1416666666667 minutes

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 minute is equal to 0.19448946515397 × 308.5 seconds.

Another way is saying that 308.5 seconds is equal to 1 ÷ 0.19448946515397 minutes.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that three hundred eight point five seconds is approximately five point one four two minutes:

308.5 s ≅ 5.142 min

An alternative is also that one minute is approximately zero point one nine four times three hundred eight point five seconds.

Conversion units

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

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.

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.
