`gamma = 1/sqrt(1-( "v" /c)^2)`

Enter a value for all fields

The **Lorentz factor** calculator computes the time dilation (**`gamma`**) measured with an atomic clock at low speeds.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**v**) Relative velocity of two observers

**Time Dilation(`gamma`):** The calculator return the dilation as a real number.

The theoretical curve for time dilation (Lorentz factor) is found using the following formula:

`gamma=1/sqrt(1-(v/c)^2)`,

where:

- `gamma` = Lorentz factor
- v = Relative velocity of two observers
- c = speed of light, the universal velocity that is the same in all frames of reference.
