What Is a Second?

A second is a unit used to measure time.

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as s, and are also sometimes abbreviated as sec. For example, 1 second can be written as 1 s or 1 sec.

How Much Is a Second?

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. According to the SI definition, the second is the duration of 9,192,631,770 oscillations of the frequency of light emitted from the atomic transition between the two hyperfine levels of the unperturbed ground state of the caesium 133 atom.^[1]

How to Convert Seconds

To convert seconds 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.^[2]

You can find the conversion factors for seconds 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.

seconds × conversion factor = result

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