About these units
The newton second (N·s) is an SI base or derived unit of momentum & impulse, equal to 1 kilogram meters per second.
The pound-force second (lbf·s) is an imperial unit of momentum & impulse, equal to 4.4482216 kilogram meters per second.
Going the other way, 1 pound-force second = 4.4482216 newton seconds. Momentum is mass times velocity, and impulse, force times time, is measured in exactly the same units: 1 N·s equals 1 kg·m/s. Physics problems, ballistics and rocket motor ratings use them.
