Both calculators run independently — change the inputs on either side to compare results.

Lorentz Transformation Calculator

Transforms the spacetime coordinates (x, t) of an event from one inertial reference frame to another moving at relativistic velocity. Used in special relativity to reconcile observations made by different observers.
