How to Convert Seconds to Microseconds

To convert a second measurement to a microsecond measurement, multiply the time by the conversion ratio.

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

microseconds = seconds × 1,000,000

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

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

How Many Microseconds Are in a Second?

There are 1,000,000 microseconds in a second, which is why we use this value in the formula above.

1 sec = 1,000,000 µs

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


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.[1]

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.


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.
