How to Convert Nanoseconds to Milliseconds

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

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

milliseconds = nanoseconds ÷ 1,000,000

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

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

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

What Is a Nanosecond?

One nanosecond is equal to 1/1,000,000,000 (one-billionth) of a second.

The nanosecond is a multiple of the second, which is the SI base unit for time. In the metric system, "nano" is the prefix for billionths, or 10-9. Nanoseconds can be abbreviated as ns; for example, 1 nanosecond can be written as 1 ns.

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.
