Frequently Asked Questions
Is this tool really free?
▼
Yes, completely free with no limits and no sign-up. Everything runs in your browser with no server costs.
Is my data sent to a server?
▼
No. All conversion math happens directly in your browser. Nothing you type is ever sent anywhere.
What units are supported?
▼
9 units: Newton-meter, Kilonewton-meter, Millinewton-meter, Kilogram-force meter, Kilogram-force centimeter, Pound-force foot (lb-ft), Pound-force inch (lb-in), Ounce-force inch, and Dyne-centimeter.
What is the difference between Nm and lb-ft?
▼
Newton-meter (Nm) is the standard metric torque unit. Pound-force foot (lb-ft) is the standard US torque unit. 1 Nm is about 0.7376 lb-ft. Car engines and tools are commonly rated in both.
What is lb-ft vs lb-in?
▼
Pound-force foot (lb-ft) is used for large torques like engine output. Pound-force inch (lb-in) is used for smaller torques like bolt tightening specs. 1 lb-ft = 12 lb-in.
What is kilogram-force meter?
▼
Kilogram-force meter (kgf-m) is the torque produced by one kilogram of weight at a one-meter lever arm. It equals about 9.807 Nm. Still used in some older specifications.
What is Dyne-centimeter?
▼
A very small torque unit from the CGS system. 1 dyne-centimeter = 0.0000001 Nm. It appears in physics and some laboratory contexts.
How accurate are the conversions?
▼
The tool uses standard conversion factors and displays up to 10 significant figures. Results are accurate for everyday, educational, and professional use.
Can I see all conversions at once?
▼
Yes. Below the main result, the tool shows the same torque in every other unit in a scrollable list.
Does it support decimals?
▼
Yes. You can type values like 0.5, 135.6, or 2.5e3. The tool handles all standard number formats.

Tips for Best Results
Nm to lb-ft quick estimate
Multiply Nm by 0.74 for a rough lb-ft estimate, or divide lb-ft by 0.74 to get Nm. For example, 100 Nm is about 74 lb-ft.
lb-ft vs lb-in
1 lb-ft = 12 lb-in. Use lb-ft for large torques (engines, lug nuts) and lb-in for small torques (electronics, small bolts).
kgf-cm for servo motors
Many hobby servo motors are rated in kgf-cm. 1 kgf-cm is about 0.0981 Nm. Use this converter to compare with Nm-rated servos.
Common automotive torques
Wheel lug nuts are typically 80 to 150 Nm (60 to 110 lb-ft). Oil drain plugs are usually 25 to 40 Nm (18 to 30 lb-ft). Always check your manual.
Do not confuse lb-ft with ft-lb
In torque, lb-ft (pound-force foot) and ft-lb (foot-pound) are the same thing. Different sources write it differently, but the value is identical.
Use the All Conversions table
Scroll below the main result to see the same torque in every other unit at once.
