0.01N/mm

Nothing on our list is smaller: a pen spring is 10× stiffer. A 10 kg weight would squash it about 9,807 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 N/m to N/mm

To convert newtons per meter to newtons per millimeter, multiply by 0.001.

Example: 10 N/m × 0.001 = 0.01 N/mm.

In the other direction, 1 N/mm = 1,000 N/m.

The units

About these units

Newtons per meter (N/m)

The SI unit: force per meter of stretch. Small for real springs, so N/mm is usual.

Newtons per millimeter (N/mm)

The practical metric unit for suspension and machine springs.
