Newton vs pound-force - what is the difference?

1 N is about 0.2248 lbf, and 1 lbf is about 4.448 N. On Earth, 1 kg mass weighs 9.807 N (about 2.205 lbf). Do not confuse lbf (force) with lb (mass).

How much force does gravity exert on me?

Force equals mass times gravity. A 70 kg person experiences about 686 N (70 kgf, 154 lbf) of gravitational force. In space with microgravity, this drops to nearly zero.

The CGS unit: 1 dyn = 10 to the negative 5 N. Mostly seen in old physics papers. Modern SI universally uses newtons.

💪 Force Converter

A kilogram is mass, a pound-force is force. On Earth 1 kg weighs ~9.81 N. On the moon it would weigh 1/6 as much. This converter distinguishes mass from force properly.
