How to convert 138 hours 3 minutes to seconds?

In order to convert 138 hours and 3 minutes to seconds we need to take each part of hours and minutes and transform them into seconds. We know that 1 hour equals 3600 seconds. Therefore to get the number of hours in seconds we need to multiply the amount of hours by 3600. In this case we have to multiply 138 hours by 3600:

We also know that 1 minute equals 60 seconds. Therefore to get the number of minutes in seconds we need to multiply the amount of minutes by 60. In this case we have to multiply 3 minutes by 60:

3m × 60s = 180 seconds

Now we have to add both amount of seconds to get the final result:

496800s + 180s = 496980 seconds

Finally we can say that 138 hr 3 min is equivalent to 496980 seconds:

Units definitions

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

Hours

An hour (symbol: h, also abbreviated hr) is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned between 3,599 and 3,601 seconds. In the modern metric system, hours are an accepted unit of time defined as 3,600 atomic seconds. There are 60 minutes in an hour, and 24 hours in a day.

Minutes

The minute is a unit of time usually 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). Although not an SI unit, the minute is accepted for use with SI units. The SI symbol for minute or minutes is min (without a dot).

Seconds

The second (symbol: s, also abbreviated: sec) is the unit of time in the International System of Units (SI), historically defined as 1⁄86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400).
