N·m to kgf·m

10 N·m = 1.019716 kgf·m.

N·m to lbf·in

10 N·m = 88.50746 lbf·in.

How to calculate Torque step by step

  1. Choose the starting unit and the target unit.
  2. Enter your value.
  3. Read the converted value, plus the conversion factor in both directions.

How to read your Torque result

Torque is force times lever arm. One newton metre is the torque from 1 N acting 1 m from the axis. Common conversions: 1 lbf·ft is about 1.35582 N·m and 1 kgf·m is exactly 9.80665 N·m.

Common mistakes when calculating Torque

  • Confusing torque in lbf·ft with work or energy in ft·lbf: same dimensions, different meaning.
  • Mixing lbf·in and lbf·ft: a factor of 12.
  • Using kgf·m as if it were N·m: it is 9.80665 times larger.

Torque FAQ

How many N·m are in a lbf·ft?

1 lbf·ft is about 1.35582 N·m.

How many lbf·ft are in 100 N·m?

About 73.76 lbf·ft.

How many lbf·in are in a lbf·ft?

What is the base unit for torque?

This converter uses newton meter (N·m) as the common base unit: every value is first converted to it and then to the target unit.

How do I convert between two torque units?

Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.

How many lbf·ft are in 1 newton meter?

1 N·m = 0.7375621 lbf·ft.

How many kgf·m are in 1 newton meter?

1 N·m = 0.1019716 kgf·m.

How many lbf·in are in 1 newton meter?

1 N·m = 8.850746 lbf·in.

Which torque units does this converter support?

It covers 10 units: newton meter (N·m), kilonewton meter (kN·m), newton centimeter (N·cm), newton millimeter (N·mm), kilogram-force meter (kgf·m), kilogram-force centimeter (kgf·cm), pound-force foot (lbf·ft), pound-force inch (lbf·in), ounce-force inch (ozf·in), dyne centimeter (dyn·cm).

How accurate is the torque converter?

Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
