A day is a unit used to measure time.

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.

How Much 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.

How to Convert Days

To convert days to another unit of time, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for days in the conversion table below.

Then, multiply the time measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

days × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
