Calculate the thrust-to-weight ratio for rockets and aircraft
📖 Thrust to Weight Ratio
Thrust-to-weight ratio (TWR) is the ratio of engine thrust to vehicle weight. A TWR greater than 1 means the vehicle can accelerate upward. Higher TWR provides better acceleration and maneuverability.

💡 Tips & Information
- TWR is a dimensionless ratio
- Formula: TWR = Thrust / (Mass × g), where g is gravitational acceleration
- TWR > 1: Vehicle can lift off and accelerate upward
- TWR < 1: Vehicle cannot lift off (thrust insufficient)
- Typical rocket TWR: 1.2-2.0 at liftoff
