How to Convert Hours to Microseconds

Calendars document the days in a month

To convert an hour measurement to a microsecond measurement, multiply the time by the conversion ratio.

Since one hour is equal to 3,600,000,000 microseconds, you can use this simple formula to convert:

microseconds = hours × 3,600,000,000

The time in microseconds is equal to the hours multiplied by 3,600,000,000.

For example, here's how to convert 5 hours to microseconds using the formula above.
5 hr = (5 × 3,600,000,000) = 18,000,000,000 µs

How Many Microseconds are in an Hour?

There are 3,600,000,000 microseconds in an hour, which is why we use this value in the formula above.

1 hr = 3,600,000,000 µs

Hours and microseconds are both units used to measure time. Keep reading to learn more about each unit of measure.


The hour is a period of time equal to 1/24 of a day or 60 minutes.

The hour is an SI accepted unit for time for use with the metric system. Hours can be abbreviated as hr; for example, 1 hour can be written as 1 hr.


The microsecond is a multiple of the second, which is the SI base unit for time. In the metric system, "micro" is the prefix for 10-6. Microseconds can be abbreviated as µs; for example, 1 microsecond can be written as 1 µs.
