Short background on the units used in this conversion.

The pound-force (lbf) is the gravitational force on one avoirdupois pound of mass at standard gravity — about 4.448 newtons.

Pounds-force rate US bolt tension, cable loads, and mechanical engineering when mass is given in pounds.

The newton is the SI unit of force — the push or pull needed to accelerate one kilogram at one meter per second squared.

Newtons quantify rocket thrust, spring ratings, and engineering loads in metric countries worldwide.
