# Warp Speed Calculators

- About

- The source code

Warp Factor Calculator is a Java Script calculator that computes
speed as a function of "warp factor" in multiples of the speed of light.

The program is operated by selecting the series version using the radio
buttons, entering a "warp factor" number that is greater than 0, and then
pressing the **Calculate** button. All entries are cleared by pressing the
**Clear** button. If the "warp factor" is too large, the output windows
will display:

**NaN** -- Not a Number

The Star Trek universe neglects relativistic effects. Time has the same
rate for both fixed and moving objects.

For the original *Classic Star Trek* series, the warp equation is generally
accepted to be:

V = C * W^{3}

in which,
C -- the speed of light ~3 x 10^{8} meters per second.
W -- the warp factor
V -- velocity through space

For *Star Trek: The Next Generation*, the generally accepted warp scale
has changed. Warp 10 is infinite speed that cannot be reached. Here the
following is used for the warp equation:
V = C * W^{3.3333 + f(W)}

in which,
f(W) = -0.5 log_{10}(10 - W), if 9.0 < W <= 10.0
f(W) = 0, otherwise

Not everyone will agree on this definition. However, it has the advantages
of being both simple and elegent.

# Next Generation Warp Speed Calculator

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 m/s.

Warp factors are calculated using Newton's method with up to 20 iterations.
