Nanoseconds to Microseconds Converter

What this converter does

This takes nanoseconds, the finest of the common time units, and lifts them up one step to microseconds. Because a microsecond is the larger of the two, the number comes down by a factor of a thousand. Enter the nanoseconds and the microseconds come straight back.

How to use it

1. Enter Nanoseconds. Type the number of nanoseconds.

Press Calculate and the equivalent in microseconds appears.

How the conversion works

There are exactly 1,000 nanoseconds in a microsecond, so to climb from nanoseconds up to microseconds you divide by 1,000. So 1,000 nanoseconds is 1 microsecond, 5,000 is 5, and 500 nanoseconds is half a microsecond. The count drops because a microsecond is the bigger unit, and the relationship is exact, a clean thousand to one.

Why step up from nanoseconds

Nanoseconds are where the hardware lives, processor cycles and memory access and the like, but they pile up fast. Add up enough nanosecond measurements, or look at something that runs for a few thousand of them, and the count gets unwieldy. Microseconds give the same information in fewer digits, a more comfortable unit once you are past the very lowest level. So this is the step you take when nanoseconds have done their job of fine measurement and you want a tidier figure to carry forward.

An example

Take 5,000 nanoseconds. Divide by 1,000 and you have 5 microseconds. A figure of 250 nanoseconds is 0.25 microseconds. The smaller result reflects the move to a larger unit.

Questions people ask

How many nanoseconds are in a microsecond?

1,000. So to convert nanoseconds to microseconds you divide by 1,000. Five thousand nanoseconds is 5 microseconds.

Why does the number get smaller?

Because a microsecond is bigger than a nanosecond, so fewer of them cover the same span. Larger unit, smaller count.

Is the conversion exact?

Yes. A microsecond is exactly 1,000 nanoseconds, so the division is precise with no rounding.

How do I go back to nanoseconds?

Multiply the microseconds by 1,000, or use a microseconds-to-nanoseconds converter.
