Type a value in N·m/deg to get it in lb·in/deg instantly.

8.851lb·in/deg

That's 57× as stiff as a self-closing hinge, while a car anti-roll bar is 8.7× stiffer. Twisting it a quarter turn would take about 90 N·m.

What it means

How stiff is that twist?

This is the rate of a torsion spring or shaft, valid while it stays elastic. Past the yield point the relationship stops being a straight line.

The math

How to convert N·m/deg to lb·in/deg

To convert newton-meters per degree to pound-inches per degree, multiply by 8.85075.

Example: 1 N·m/deg × 8.85075 = 8.85075 lb·in/deg.

In the other direction, 1 lb·in/deg = 0.112985 N·m/deg.
