Kilograms-force per millimeter to newtons per millimeter
Type a value in kgf/mm to get it in N/mm instantly.
98.07N/mm
That's 3.3× as stiff as car suspension, while a truck leaf spring is 2× stiffer. A 10 kg weight would squash it about 1 mm.
What it means
How much does it give?
Real springs only follow this straight line within their working range. Past that they bind or take a permanent set.
The math
How to convert kgf/mm to N/mm
To convert kilograms-force per millimeter to newtons per millimeter, multiply by 9.80665.
Example: 10 kgf/mm × 9.80665 = 98.0665 N/mm.
In the other direction, 1 N/mm = 0.101972 kgf/mm.
