Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Relativity
Lorentz Factor Calculator
Compute the Lorentz factor γ = 1/√(1 − (v/c)²), the central quantity of special relativity that scales time dilation, length contraction, relativistic mass, momentum, and energy. Returns a dimensionless number ≥ 1.
Fill in the required fields to see your result.
Relativity
Time Dilation Calculator
Compute the time experienced by a stationary observer for a moving clock that ticks through a given proper time, using special relativity. Returns the dilated time interval in the same units as the proper-time input.
