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.
milliseconds = (5 d × 86,400,000) = 432,000,000 ms
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.
