Convert Pounds-force to Newtons
lbf to N · force conversion
What are pounds-force and newtons?
A pound-force is the gravitational force on one pound of mass, about 4.448 N. The newton is the SI unit of force, the force to accelerate 1 kg at 1 m/s². For reference: holding a 1 kg object takes about 9.8 N of force against gravity.
How to convert pounds-force to newtons
1 lbf = 4.44822 N. To convert, multiply the number of pounds-force by 4.44822. For example, 5 lbf = 22.2411 N, and 20 lbf = 88.9644 N. To go the other way, multiply newtons by 0.224809 (since 1 N = 0.224809 lbf).
