About Converting Microseconds to Nanoseconds

Microsecond and Nanosecond are both everyday units of duration, and converting between them is one of the most routine calculations there is — scheduling, project planning, and billing all depend on it. Specifically: Microsecond is 0.000001 second units, and nanosecond is 1e-9 second units.

Formula

nanoseconds = microseconds × 1000

This factor comes from each unit's defined relationship to the category's base unit: 1 microsecond equals 0.000001 base units, and 1 nanosecond equals 1e-9 base units, so dividing one by the other gives the direct microsecond-to-nanosecond factor of 1000.

Simple example

1 us × 1000 = 1,000 ns

1 microsecond = 1,000 nanoseconds.

Real-world example

24 us × 1000 = 24,000 ns

24 microseconds = 24,000 nanoseconds.

Frequently asked questions

How many nanoseconds are in 1 microsecond?

1 microsecond equals 1,000 nanoseconds, using the exact defined conversion factor rather than an estimate.

How do I convert microsecond to nanosecond?

Multiply the microsecond value by 1000. The converter above does this instantly to whatever precision you set.

How do I convert nanosecond back to microsecond?

Use the reverse factor: 1 nanosecond equals 0.001 microseconds. You can also use the swap control in the converter above to flip the direction instantly.

What is a microsecond?

Microsecond (us) is a unit of time.

What is a nanosecond?

Nanosecond (ns) is a unit of time.

Is the microsecond to nanosecond conversion exact?

Yes. Both microsecond and nanosecond are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
