Delta-V Calculator

dv = Ve * ln(m0 / mf)

Exhaust Velocity (m/s)

Wet Mass / Initial Mass (kg)

Dry Mass / Final Mass (kg)

Formula

dv = Ve * ln(m0 / mf)

What is delta-v?

Delta-v is the total change in velocity a rocket can achieve. It determines what orbital maneuvers are possible.

What is the Tsiolkovsky equation?

dv = Ve * ln(m0/mf). It relates delta-v to exhaust velocity and mass ratio.
