Force Converter
Converts force between SI and imperial units. A newton is the force that accelerates one kilogram at one metre per second squared — roughly the weight of a small apple on Earth.

The formula
result = value × (from factor ÷ to factor)
Each force unit is defined by its size relative to the newton, so converting between any two is a single multiplication.
Every force unit

Frequently Asked Questions
How many newtons is one pound-force?
4.44822 N. Conversely, one newton is 0.2248 lbf.
What is the difference between kg and kgf?
A kilogram is mass; a kilogram-force is the weight of that mass in standard gravity — 9.80665 N. They are numerically interchangeable on Earth but not the same quantity.
How much force does a 70 kg person exert standing still?
About 687 N — that is 70 × 9.80665, or roughly 154 lbf.
