# Microseconds to Seconds Conversion

Enter the time in microseconds below to get the value converted to seconds.

Results in Seconds: 1 µs = 1.0E-6 sec
Hint: use a scientific notation calculator to convert E notation to decimal

## How to Convert Microseconds to Seconds To convert a microsecond measurement to a second measurement, divide the time by the conversion ratio.

Since one second is equal to 1,000,000 microseconds, you can use this simple formula to convert:

seconds = microseconds ÷ 1,000,000

The time in seconds is equal to the microseconds divided by 1,000,000.

For example, here's how to convert 5,000,000 microseconds to seconds using the formula above.
5,000,000 µs = (5,000,000 ÷ 1,000,000) = 5 sec

## Microseconds

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.

## Seconds

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. According the to SI definition, the second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the unperturbed ground state of the caesium 133 atom.

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as sec; for example, 1 second can be written as 1 sec.
