What does this tool do?
The newton is the SI unit of force, while pound-force is the force of one pound mass under standard gravity. This converter covers the units used on equipment labels and engineering data sheets.
The Formula
Pound-force = Newtons ÷ 4.4482216; newtons = pound-force × 4.4482216Frequently Asked Questions
Is pound-force the same as pound mass?
No. A pound is a mass, while pound-force is the weight of that mass in standard gravity. On Earth 1 lbm weighs about 1 lbf, which is why the numbers are often confused.
What is a poundal?
A poundal is the force that accelerates a one-pound mass at one foot per second squared, equal to about 0.1383 newtons. It is rarely used outside older engineering texts.
