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.

Elapsed time at a body T0
    1. sec
Relative velocity v
    1. km/s
    2. ≦c

Elapsed time at observer T

    Purpose of use
    In my Air Force career flying for over 21 years, curious as to how much I actually aged.
    [2]  2021/04/16 13:08   Male / 40 years old level / Others / Useful /
    Purpose of use
    I'm trying to recalibrate my time pod. I finally made it to a century with a primitive version of the internet, please somebody hel

    Purpose of use
    learn about time dilation for fun
    [4]  2021/02/17 19:18   Male / 30 years old level / A teacher / A researcher / Useful /
    Purpose of use
    Calculate the time dilation of Perseverance on it's way to Mars.
    [5]  2021/01/20 06:18   Male / 30 years old level / Others / A little /
    Purpose of use
    Calculating time difference between someone living at equator vs artic circle.
    [6]  2020/12/14 03:07   Male / 20 years old level / Others / Useful /
    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
    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.
    [7]  2020/12/06 09:48   Male / 60 years old level or over / A retired person / Useful /
    Purpose of use
    Developing a humorous explanation of how I managed to do the Saturday crossword in about 60% of my average time.
    [8]  2020/11/18 10:27   Male / 50 years old level / An office worker / A public employee / Useful /
    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.
    [9]  2020/11/16 14:56   Male / Under 20 years old / Self-employed people / Very /
    Purpose of use
    General curiosity and not wanting to do calculations/make my own calculator.
    [10]  2020/09/05 11:25   Male / 60 years old level or over / - / Very /
    Purpose of use
    To calculate how old someone travelling for a long time at relativistic speeds really is. Fiction writing.
