# Hours to microseconds

**1 hour in microseconds: 1 h = 3,600,000,000 µs**

µs = h × 3,600,000,000

To convert hours to microseconds, multiply by 3,600,000,000. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is µs = h × 3,600,000,000. Both units measure time, so the conversion is a fixed factor that never changes.

## Common questions

### How many microseconds are in one hour?

One hour equals 3,600,000,000 microseconds. µs = h × 3,600,000,000.

### How do you convert hours to microseconds?

Use µs = h × 3,600,000,000. So 10 h is 36,000,000,000 µs.

### How many hours are in one microsecond?

One microsecond equals 2.778 × 10^-10 hours, which is the reverse of the conversion above.
