How to Convert Days to Milliseconds
Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications.
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:
The time in milliseconds is equal to the time in days multiplied by 86,400,000.
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.
