# Special relativity (time dilation) Calculator

## Calculates the time dilation of a body moving for some time with some relative velocity with respect to the observer. | ||

- Purpose of use
- Calculating time difference between someone living at equator vs artic circle.

- 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.

- Purpose of use
- Developing a humorous explanation of how I managed to do the Saturday crossword in about 60% of my average time.

- Purpose of use
- Curious about the time dilation effect of our current speed of travel on Earth as it moves on it's axis, around the Sun, around the galaxy and through the universe versus a hypothetical stationary observer.

- Purpose of use
- General curiosity and not wanting to do calculations/make my own calculator.

- Purpose of use
- To calculate how old someone travelling for a long time at relativistic speeds really is. Fiction writing.

- Purpose of use
- calculating elapsed time for relativistic space travellers
- Comment/Request
- Would be handy to be able to enter speed as a fraction of c. But overall this is quite handy as-is

- Purpose of use
- Looking for a way to calculate time dilations either by putting in the time difference or by using a % of C; I'm watching a Game Theory episode and MatPat severely goofed, somehow missing that you can have a decimal in a % of C.
- Comment/Request
- Allow at least entering a % of C to calculate the time dilation.

- Purpose of use
- The concept of Time is just mind-blowing!
- Comment/Request
- Fine as is.
