1 nanosecond (ns) = 0.001 microseconds (µs). To convert, divide by 1,000: µs = ns ÷ 1,000. For example, 500 ns = 0.5 µs.
µs = ns ÷ 1,000

The two units
Nanosecond (ns). One billionth of a second, the scale of CPU cycles.
Microsecond (µs). One millionth of a second.
Because both units are defined in terms of the same base unit, the factor 0.001 is exact, not a rounded measurement.

Questions people ask
- How many microseconds are in a nanosecond?
- 0.001, exactly.
- How do you convert nanoseconds to microseconds?
- µs = ns ÷ 1,000. It is the same as dividing by 1,000.
- How do you convert microseconds back to nanoseconds?
- ns = µs × 1,000. See microseconds to nanoseconds.
