To convert a measurement in microseconds to a measurement in milliseconds, divide the time by the following conversion ratio: 1,000 microseconds/millisecond.

Since one millisecond is equal to 1,000 microseconds, you can use this simple formula to convert:

milliseconds = microseconds ÷ 1,000

The time in milliseconds is equal to the time in microseconds divided by 1,000.

For example, here's how to convert 5,000 microseconds to milliseconds using the formula above.
milliseconds = (5,000 µs ÷ 1,000) = 5 ms

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.

What Is a Millisecond?

One millisecond is equal to 1/1,000 of a second or 1,000 microseconds.

The millisecond is a multiple of the second, which is the SI base unit for time. In the metric system, "milli" is the prefix for thousandths, or 10-3. Milliseconds can be abbreviated as ms; for example, 1 millisecond can be written as 1 ms.
