## How to Convert Days to Microseconds

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

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

microseconds = days × 86,400,000,000

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

For example, here's how to convert 5 days to microseconds using the formula above.
microseconds = (5 d × 86,400,000,000) = 432,000,000,000 µs

### How Many Microseconds Are in a Day?

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

1 d = 86,400,000,000 µs

## 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 Microsecond?

One microsecond is equal to 1/1,000 of a millisecond or 1,000 nanoseconds.

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 millionths, or 10-6. Microseconds can be abbreviated as µs; for example, 1 microsecond can be written as 1 µs.
