Convert Pounds-force to Kilonewtons
lbf to kN · force conversion
What are pounds-force and kilonewtons?
A pound-force is the gravitational force on one pound of mass, about 4.448 N. A kilonewton is 1,000 newtons, used in structural and mechanical engineering. For reference: holding a 1 kg object takes about 9.8 N of force against gravity.
How to convert pounds-force to kilonewtons
1 lbf = 0.00444822 kN. To convert, multiply the number of pounds-force by 0.00444822. For example, 5 lbf = 0.0222411 kN, and 20 lbf = 0.0889644 kN. To go the other way, multiply kilonewtons by 224.809 (since 1 kN = 224.809 lbf).

FAQ
What is 1 lbf in kN?
1 lbf = 0.00444822 kN. To convert any amount, multiply the number of pounds-force by 0.00444822.
How do I convert kilonewtons back to pounds-force?
Go the other way: 1 kN = 224.809 lbf, so multiply kilonewtons by 224.809 to get pounds-force.
Is a pounds-force bigger than a kilonewton?
No — 1 lbf is the smaller unit, equal to 0.00444822 kN (it takes 224.809 lbf to make one kN).
Are these force conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
