## How to Convert Seconds to Milliseconds

To convert a second measurement to a millisecond measurement, multiply the time by the conversion ratio. One second is equal to 1,000 milliseconds, so use this simple formula to convert:

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

**For example,**here's how to convert 5 seconds to milliseconds using the formula above.

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

## Seconds

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. The SI defines the second as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as *sec*, for example 1 second can be written as 1 sec.

## Milliseconds

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 10^{-3}. Milliseconds can be abbreviated as *ms*, for example 1 millisecond can be written as 1 ms.
