How is Force Converter: Newtons, kgf, lbf and Dynes calculated?

Use F = ma; 1 kgf = 9.80665 N. Convert N, kN, kgf, lbf and dynes. Use standard gravity correctly and avoid confusing kilogram mass with kilogram-force.

How do I calculate this example: 10 kgf?

98.0665 N. This is a calculated example under the model stated above; it is not a measured component specification.

Which units does Force Converter: Newtons, kgf, lbf and Dynes use?

N, kN, mN, dyn, kgf, gf, lbf, ozf. Convert prefixes before substituting values; keep the input and output units attached to every number.

Are kg and kgf the same?

No. kg measures mass; kgf measures force defined using standard gravity. A mass produces different weight at a different gravitational acceleration.

How many N are in 1 lbf?

1 lbf = 4.4482216152605 N; 1 dyn = 0.00001 N.

Can I convert N directly to N·m?

No. N is force; N·m can describe torque. Torque also requires the perpendicular lever arm: τ = F × r.
