About these units
Pound-forces (lbf): A pound-force is the weight of one pound in standard gravity, about 4.448 newtons.
Kilonewtons (kN): A kilonewton is 1,000 newtons, used for loads on structures, anchors and lifting gear.
Frequently asked questions
How many kilonewtons are in 1 pound-force?
1 pound-force (lbf) equals 0.004448221615 kilonewtons (kN).
How do I convert lbf to kN?
Multiply the value in pound-forces by 0.004448221615. For example, 5 lbf × 0.004448221615 = 0.02224110808 kN.
How do I convert kilonewtons back to pound-forces?
Multiply by 224.8089431 (or divide by 0.004448221615). 1 kN = 224.8089431 lbf.
What is a pound-force?
