## How to Convert Days to Milliseconds

To convert a measurement in days to a measurement in milliseconds, multiply the time by the following conversion ratio: 86,400,000 milliseconds/day.

Since one day is equal to 86,400,000 milliseconds, you can use this simple formula to convert:

milliseconds = days × 86,400,000

The time in milliseconds is equal to the time in days multiplied by 86,400,000.

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

### How Many Milliseconds Are in a Day?

There are **86,400,000** milliseconds in a day, which is why we use this value in the formula above.

1 d = 86,400,000 ms

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

## What Is a Day?

One day is the time it takes for the Earth to complete a single 360-degree rotation about its axis. There are 24 hours in a day.

The day is an SI accepted unit for time for use with the metric system. Days can be abbreviated as *d*; for example, 1 day can be written as 1 d.

## 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.
