## How to Convert Hours to Microseconds

To convert a measurement in hours to a measurement in microseconds, multiply the time by the following conversion ratio: 3,600,000,000 microseconds/hour.

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 time in hours multiplied by 3,600,000,000.

For example, here's how to convert 5 hours to microseconds using the formula above.
microseconds = (5 hr × 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

## What Is an Hour?

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 (plural hrs); for example, 1 hour can be written as 1 hr, and 2 hours can be written as 2 hrs.

## What Is a Microsecond?

One microsecond is equal to 1/1,000 of a millisecond or 1,000 nanoseconds.

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 millionths, or 10-6. Microseconds can be abbreviated as µs; for example, 1 microsecond can be written as 1 µs.
