ā³ Time Dilation Calculator
Move fast and time slows down. Calculate the Lorentz factor for any speed.
Results
- Lorentz factor Ī³
- 2.29416
- Time for stationary observer
- 2.29416
- 0.9c check: Ī³ ā 2.294
How it works
Ī³ = 1 / ā(1 ā vĀ²/cĀ²) Ā· dilated time = Ī³ Ć proper time
Einstein showed that a moving clock ticks slower as seen from a stationary frame. At everyday speeds the effect is tiny (but GPS satellites must correct for it); near light speed it becomes enormous.
Assumptions: Special relativity, inertial frames, no gravity.
