Convert Pound-forces to Kilonewtons (lbf to kN)
1 lbf = 0.00444822162 kN. Convert pound-forces to kilonewtons with the exact factor, a common-values table and a free converter.
Conversion factor
kN = lbf × 0.00444822162
1 lbf = 0.00444822162 kN
Multiply by 0.00444822162 kN to go from pound-forces to kilonewtons, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.

Frequently asked questions
How many kilonewtons are in one pound-force?
One pound-force is 0.00444822162 kN, so 100 lbf is 0.444822162 kN.
What is the formula to convert pound-forces to kilonewtons?
kN = lbf × 0.00444822162. Multiply the value in pound-forces by 0.00444822162 to get kilonewtons.
How do I convert kilonewtons back to pound-forces?
lbf = kN × 224.808943, so 1 kN is 224.808943 lbf. The kN to lbf page carries the same table in that direction.
