Converting Pounds to Newtons

Filed under: Teacher Tips, Resources, Energy, Machines, and Motion — Justin @ 8:41 am

Another teacher and I were just discussing the conversion between pounds and Newtons. The actual English unit is pound-force.

1 pound-force = 4.4482216 Newtons

You can use this handy calculator to perform a grossly unnecessary number of different force conversions.

You can also check your answer by “converting” Newtons to Kilograms, then multiplying by 2.2 to convert to pounds.

1 kilogram-force = 9.80665 newton

1 kilogram-force = 2.2046226 pound-force

(This isn’t a true conversion because it assumes you’re in Earth’s gravity; otherwise, it’s not valid.)
