Thrust-to-Weight Ratio Calculator
Divide engine thrust by vehicle weight to assess performance.
Ignores drag and real flight conditions.
Examples
- Thrust 100,000 N, weight 40,000 N ⇒ 2.5 ratio
- Thrust 500,000 N, weight 450,000 N ⇒ 1.11 ratio
FAQ
What does a ratio over 1 mean?
The vehicle can accelerate upward.
Can I use pounds-force?
Yes, if thrust and weight use the same units.
Does weight include fuel?
Use the total weight at the time of measurement.
Additional Information
- High thrust-to-weight ratios are key for launch vehicles.
- Ratio is dimensionless; use consistent units for thrust and weight.
