Kilonewtons to thrust-to-weight ratio
Type a value in kN to get it in T/W instantly.
0.1748T/W
That's 8× as much thrust as a business-jet engine, while a fighter engine on afterburner is 1.08× more. That is enough to hold up about 12,240 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 kN to T/W
Thrust-to-weight is thrust ÷ (mass × 9.807 m/s²). The figures below use the vehicle chosen above.
Example: 120 kN = 0.174808 T/W.
Thrust-to-weight below assumes Airliner, 70 t. Change it above and those figures update.
