Lorentz Factor Calculator

Calculate the Lorentz factor (γ) and relativistic effects from velocity

Velocity Input Type:

Velocity (as decimal, e.g., 0.9 for 90% of c):

Speed of light c = 299,792,458 m/s = 1,079,252,848.8 km/h

Lorentz factor: γ = 1 / √(1 - v²/c²)

Time dilation: Δt' = γΔt

Length contraction: L = L₀/γ

Relativistic kinetic energy: KE = (γ - 1)mc²
