- Purpose of use
- to determine what fraction of c a muon would need to travel in an accelerator to have a decay rate on the order of seconds relative to outside observers
- Comment/Request
- This calculator would infinitely improved if you could manipulate units, rearrange input/output parameters, and if it had a key for acceptable inputs or a broader range of acceptable inputs to convey the same meaning. For example if one could input in units of a fraction of c or different units besides km/s and intervals of time other than seconds. Also I had to discover your acceptable input notation for scientific notation by trail and error.

Otherwise it was helpful and accurate.
