The kilonewton (kN) equals 1,000 newtons, used in structural engineering to express building loads, bridge capacities, and material strength ratings. A typical passenger car weighs about 10–15 kN, and building codes specify design loads in kN per square meter. One kilonewton equals approximately 224.8 pound-force.

Ounce-force (ozf) equals approximately 0.278 newtons, the imperial unit for small force measurements in precision engineering, spring calibration, and micro-mechanical testing. It is particularly useful for measuring trigger pull weights, small spring tensions, and delicate instrument calibrations. One ounce-force equals about 1/16 of a pound-force.
