This website is here to quickly help you with everyday unit conversions in experimental
physics working with electrons and photons. You can input any property into the calculator and the other corresponding properties are calculated. The small script is based on an
equation module, mathjs and katex to provide full calculation capabilities! For each input, you can
decide between a relativistic electron with
its matter-wave properties or a photon.

Disclaimer: This is just a beta! The results of this calculator were tested thoroughly.
However, you should not rely on the correctness of any calculation on this website for critical purposes
(i.e. financial, grants, medical, safety).
If things of value are at stake, please verify the calculator output with a credible source.

Just try the following examples to see some of the possibilities:
