Rocket Thrust Calculator

F = mass_flow_rate * exhaust_velocity

Mass Flow Rate (kg/s)

Exhaust Velocity (m/s)

Formula

F = mdot x Ve | Isp = Ve / g

How is rocket thrust calculated?

Thrust equals mass flow rate times exhaust velocity: F = mdot * Ve.

What is specific impulse?

Specific impulse (Isp) measures engine efficiency. It equals exhaust velocity divided by g (9.81 m/s^2).
