Rocket Equation Calculator
Calculate delta-v from the Tsiolkovsky rocket equation using mass ratio and exhaust velocity. Enter values for instant results with step-by-step formulas.
Formula
ฮv = vโ ร ln(mโ/mโ)
The Tsiolkovsky rocket equation relates delta-v to exhaust velocity and mass ratio. vโ = Isp ร gโ. Higher mass ratio = more delta-v but diminishing returns.
Frequently Asked Questions
