Pound-feet per second to kilogram-meters per second
Type a value in lb·ft/s to get it in kg·m/s instantly.
13.83kg·m/s
That's 1.54× as much momentum as a kicked football, while a walking adult is 7.1× more. Stopping that in one second takes about 13.83 N of force.
Convert the other way: kg·m/s to lb·ft/s
What it means
What carries that much?
Momentum is mass times velocity. Impulse, in newton-seconds, is the same quantity seen as a force acting over time.
The math
How to convert lb·ft/s to kg·m/s
To convert pound-feet per second to kilogram-meters per second, multiply by 0.138255.
Example: 100 lb·ft/s × 0.138255 = 13.8255 kg·m/s.
In the other direction, 1 kg·m/s = 7.23301 lb·ft/s.
