How to Convert Microseconds to Hours

To convert a microsecond measurement to an hour measurement, divide 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:

hours = microseconds ÷ 3,600,000,000

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

For example, here's how to convert 5,000,000,000 microseconds to hours using the formula above.
5,000,000,000 µs = (5,000,000,000 ÷ 3,600,000,000) = 1.388889 hr

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


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.


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.
