About Force Converter
The Force Converter turns a single force value into its equivalent across every common unit at once.
Engineers, physics students and makers constantly switch between metric and imperial force units, and doing it by hand invites slipped decimal points and forgotten gravity constants.
Type a number, choose its unit, and this tool instantly shows the same force expressed in newtons, kilonewtons, dynes, pound-force, kilogram-force, ounce-force and poundals.
The newton is the SI unit, defined as the force that accelerates one kilogram at one metre per second squared.
Kilogram-force and pound-force are gravitational units, tied to standard gravity (9.80665 m/s²), which is exactly where manual conversions go wrong.
The dyne belongs to the older CGS system and the poundal to the absolute foot-pound-second system, both of which still appear in textbooks and legacy specifications.
Having all of them side by side makes spotting the right magnitude effortless.
Negative values are allowed because force has direction, and zero is handled cleanly.
Every conversion runs locally in your browser using exact, published conversion factors, so nothing is uploaded and the tool keeps working offline once the page has loaded.
FAQ
How is kilogram-force related to newtons?
One kilogram-force equals 9.80665 newtons, the force standard gravity exerts on a one-kilogram mass. The converter uses that exact constant.
Can I convert negative forces?
Yes. Force is a vector, so a negative sign simply denotes direction. Negative and zero values both convert correctly.
Are the conversion factors exact?
They use the internationally published definitions for each unit, rounded only at display so results are accurate to many significant figures.
