Convert force between newton (N, SI base), kilonewton (kN), dyne (dyn, CGS = 10⁻⁵ N), pound-force (lbf = 4.4482216152605 N), kilogram-force (kgf = 9.80665 N), and poundal (pdl = 0.138254954376 N). All factors derive from the exact defining constants 1 lb = 0.45359237 kg, 1 ft = 0.3048 m, and standard gravity g₀ = 9.80665 m/s². Converts via newton to the target unit and lists the equivalent value in all six units. Reference: 1 kg of mass on Earth ≈ 9.80665 N (1 kgf); an adult weighs ≈ 700 N.

Tool usage guide
Convert force values between newtons (N), kilonewtons (kN), dynes (dyn), pound-force (lbf), kilogram-force (kgf), and poundals (pdl). Enter a value, choose the input and output units, set decimal places from 0 to 10, and receive the converted result plus equivalent values in all six units.
Background
A physics exercise gives a force as 1 kgf and requires the answer in SI units.
Problem
Find the equivalent force in newtons while retaining useful precision.
How to use
Set Input unit to kgf, enter 1, set Output unit to N, and choose 6 decimal places.
inputUnit: kgf; value: 1; outputUnit: N; decimalPlaces: 6Outcome
The result is 1 kgf = 9.80665 N. The output also lists 0.009807 kN, 980665 dyn, 2.204623 lbf, and 7.093162 poundal.
Background
A small thrust specification is recorded as 100 lbf, but the engineering calculation uses newtons.
Problem
Convert the thrust value to SI force units and review its other equivalents.
How to use
Set Input unit to lbf, enter 100, set Output unit to N, and choose 6 decimal places.
It supports N, kN, dyn, lbf, kgf, and poundal (pdl).
1 kgf equals 9.80665 N under standard gravity.
Yes. The converter uses 1 lbf = 4.4482216152605 N.
Yes. Negative values can represent force in the opposite direction.
You can choose from 0 to 10 decimal places.
inputUnit: lbf; value: 100; outputUnit: N; decimalPlaces: 6Outcome
The result is 100 lbf = 444.822162 N, with equivalent values of 0.444822 kN, 44482216.152605 dyn, 45.359237 kgf, and 3217.404828 poundal.
Background
A force of -0.5 kN represents a load acting opposite to the chosen positive direction.
Problem
Express the signed force in pound-force while preserving its direction.
How to use
Select kN as the Input unit, enter -0.5, select lbf as the Output unit, and set the desired decimal places.
Outcome
The converter returns a negative lbf value, preserving the opposite-direction sign, and also provides equivalent values in N, kN, dyn, kgf, and poundal.
