To convert a measurement in milliseconds to a measurement in microseconds, multiply 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:

microseconds = milliseconds × 1,000

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

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

How Many Microseconds Are in a Millisecond?

There are 1,000 microseconds in a millisecond, which is why we use this value in the formula above.

1 ms = 1,000 µs

Milliseconds and microseconds are both units used to measure time. Keep reading to learn more about each unit of measure.

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.

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.
