How to Convert Microseconds to Days

Calendars document the days in a month

To convert a microsecond measurement to a day measurement, divide the time by the conversion ratio. One day is equal to 86,400,000,000 microseconds, so use this simple formula to convert:

days = microseconds ÷ 86,400,000,000

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

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

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


The microsecond is a multiple of the second, which is the SI base unit for time. In the metric system, "micro" is the prefix for 10-6. Microseconds can be abbreviated as µs; for example, 1 microsecond can be written as 1 µs.


One day is the time it takes for the Earth to complete a single rotation around its axis in relation to the Sun. 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 day; for example, 1 day can be written as 1 day.
