1 hour and 30 minutes in seconds

1 hour 30 minutes equals 5400 seconds

How to convert 1 hour 30 minutes to seconds?

In order to convert 1 hour and 30 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 1 hour by 3600:

1h × 3600s = 3600 seconds

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 30 minutes by 60:

30m × 60s = 1800 seconds

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

3600s + 1800s = 5400 seconds

Finally we can say that 1 hr 30 min is equivalent to 5400 seconds:

1 hour and 30 minutes = 5400 seconds

One hour and thirty minutes is equal to five thousand four hundred 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).
