How to Convert Milliseconds to Days

To convert a measurement in milliseconds to a measurement in days, divide 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:

days = milliseconds ÷ 86,400,000

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

For example, here's how to convert 50,000,000 milliseconds to days using the formula above.
days = (50,000,000 ms ÷ 86,400,000) = 0.578704 d

Milliseconds and days 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.

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.
