This calculator allows you to either find the speed corresponding to a certain warp factor, or the warp factor corresponding to a certain speed. Results may vary in accuracy and are limited by the precision of your software.

To find what speed corresponds to a certain warp factor, enter the warp factor and press “Find speed.” Results will be displayed in multiples of the speed of light and will always be exact.

To find what warp factor corresponds to a certain speed, enter the speed (in multiples of the speed of light) and press “Find warp.” Results from this calculation may vary in accuracy due to the methods used to determine them. To check the accuracy, press “Find speed” once the warp factor has been displayed to see if the result is close to the speed you originally entered.

The calculator determines the speed according to the warp scale used in Star Trek: The Next Generation; Deep Space 9; and Voyager. Warp speeds in the original series were based on a different scale.

The speed of light in a vacuum is 299,792,458 ms^{–1}.

Warp factors are calculated using Newton’s method with up to 20 iterations. This page, its contents and code are protected by copyright. © 1998-2023, Martin A. Shields.
