How to Convert N*M to OZF*IN (Newton meter to Ounce-force inch)?

We can convert newton meter to ounce-force inch by using an example.

Example:

Convert 20 Newton meter to Ounce-force inch?

We know 1 Newton meter = 141.6119690 ounce-force inch; 1 Ounce-force inch = 0.0070615 newton meter.

20 newton meter = ___ozf*in

20 × 141.6119690 = 2832.23938 ozf*in (we know 1 newton meter = 141.6119690 ounce-force inch)

Answer:

20 newton meter = 2832.23938 ounce-force inch

Newton-Meters to Ounce-Force Inches: Miniature Torque in Imperial

Ounce-force inches (ozf·in) is the imperial unit for very small torques, prevalent in American stepper motor datasheets, small actuator specs, and precision instrument calibration. Since 1 N·m = 141.61 ozf·in, this conversion handles the transition between metric engineering and US miniature component specifications.

  1. Start with the torque in N·m.
  2. Multiply by 141.61.
  3. The result is the torque in ozf·in.
  4. Example: 0.5 N·m × 141.61 = 70.8 ozf·in.
💡 Tip: For NEMA stepper motors: multiply N·m by 141.6 to convert metric datasheets to the oz·in values commonly listed on US supplier sites.

N·m to ozf·in for Small Motors and Actuators

Miniature torque specifications in metric and imperial:

Newton meterOunce-force inch
0.01 N·m1.4 ozf·in
0.05 N·m7.1 ozf·in
0.1 N·m14.2 ozf·in
0.2 N·m28.3 ozf·in
0.4 N·m56.6 ozf·in
0.5 N·m70.8 ozf·in
1 N·m141.6 ozf·in
2 N·m283.2 ozf·in

Worked Examples: N·m to ozf·in

Question 1: A NEMA 17 stepper motor is rated at 0.44 N·m. What is this in ozf·in for a US supplier listing?

Solution:

ozf·in = N·m × 141.61

= 0.44 × 141.61

= 62.3 ozf·in

Answer: 0.44 N·m = 62.3 ozf·in — a standard 3D printer motor specification.

Question 2: A precision dial indicator spring provides 0.02 N·m of restoring torque. Express in ozf·in.

Solution:

ozf·in = N·m × 141.61

= 0.02 × 141.61

= 2.83 ozf·in

Answer: 0.02 N·m = 2.83 ozf·in — delicate torque for instrument mechanisms.

Question 3: A small gear motor outputs 0.3 N·m. Convert to ozf·in.

Solution:

ozf·in = N·m × 141.61

= 0.3 × 141.61

= 42.5 ozf·in

Answer: 0.3 N·m = 42.5 ozf·in — suitable for a robotic gripper actuator.

Practice: N·m to ozf·in

Try solving these on your own to test your understanding:

  1. Convert 0.6 N·m to ozf·in. (Answer: 85.0 ozf·in)
  2. A motor produces 1.5 N·m. What is this in ozf·in? (Answer: 212.4 ozf·in)
  3. Convert 0.08 N·m to ozf·in. (Answer: 11.3 ozf·in)

  5. Convert 0.25 N·m to ozf·in. (Answer: 35.4 ozf·in)

Stepper Motor Datasheets: Navigating oz·in Specs

US stepper motor suppliers universally list holding torque in oz·in (shorthand for ozf·in). Common values: NEMA 11 (5-15 oz·in), NEMA 14 (20-35 oz·in), NEMA 17 (40-90 oz·in), NEMA 23 (100-400 oz·in), and NEMA 34 (500-1,500 oz·in). When comparing to Chinese or European datasheets in N·m, divide oz·in by 141.6 to get N·m, or multiply N·m by 141.6 for oz·in.

Converting Between ozf·in and lbf·in

Since 16 ounces = 1 pound, you can convert ozf·in to lbf·in by dividing by 16. So 141.6 ozf·in (= 1 N·m) equals 8.85 lbf·in — confirming the N·m to lbf·in factor of 8.8507. This relationship helps cross-check conversions: if a motor specs say 64 ozf·in, that is 4 lbf·in or about 0.45 N·m.

Key Takeaways

  • 1 N·m = 141.61 ozf·in (multiply N·m by 141.61).
  • US stepper motor datasheets use oz·in as the standard torque unit.
  • NEMA 17 motors: typically 40-90 oz·in (0.28-0.64 N·m).
  • 16 ozf·in = 1 lbf·in (standard ounce-to-pound relationship).
  • Divide oz·in by 141.6 to convert back to N·m.
