Tons-force (US) to kilonewtons
Type a value in tonf to get it in kN instantly.
1,067.573kN
That's 1.26× as much thrust as a Falcon 9 Merlin engine, while a Starship Raptor engine is 2.2× more. That is enough to hold up about 108,900 kg against gravity.
What it means
How much push is that?
Engine figures are typical published ratings; afterburning, altitude and throttle all change them. Rocket thrust is at sea level.
The math
How to convert tonf to kN
To convert tons-force (US) to kilonewtons, multiply by 8.89644.
Example: 120 tonf × 8.89644 = 1,067.57 kN.
In the other direction, 1 kN = 0.112404 tonf.
Thrust-to-weight below assumes Airliner, 70 t. Change it above and those figures update.
