Insert the information in the form and the calculator will determine the time dilation.

What is the time dilation?

The time dilation is the difference in elapsed time as measured by two clocks.

How to calculate time dilation?

To calculate time dilation you should use the following formula:
time dilation = elapsed time at body / √( 1 - ((relative velocity * 1000) / c)²)
where:
c = 299792458

Why use time dilation?

The time dilation has a lot of practical uses and one of them is keeping the clocks on GPS satellites accurate.
