Frequently asked questions
How do I convert Nm to lb-ft?
Divide Newton-metres by 1.35582 to get pound-feet. For example, 400 Nm ÷ 1.35582 = 295 lb·ft.
How do I convert lb-ft to Nm?
Multiply pound-feet by 1.35582 to get Newton-metres. For example, 300 lb·ft × 1.35582 = 407 Nm.
What is torque?
Torque is the rotational equivalent of linear force — it is the tendency of a force to rotate an object about an axis. Torque = Force × Distance from the pivot. Engine torque determines a vehicle's pulling and acceleration power.
What is the difference between torque and horsepower?
Torque is a force that causes rotation (measured in Nm or lb·ft). Horsepower is the rate at which work is done (power). They are related: HP = Torque (lb·ft) × RPM ÷ 5,252. High torque at low RPM = good for towing; high HP at high RPM = good for top speed.

How to use the torque
Use this torque to onvert between newton-metres, pound-foot, pound-inch, kilogram-force·metre, and more torque units. Enter your values above and get your result in seconds. The tool is free, works on all devices, and keeps your data private — nothing is stored or shared.
How the torque works
The torque converter uses standard formulas used in unit conversion in science, engineering, cooking, and everyday use. Enter your inputs, and the tool calculates the result instantly in your browser. No server-side processing means your data stays on your device. Results update in real time as you change inputs.
Newton-metres and pound-feet
Newton-metres (Nm) is the SI unit of torque. Pound-feet (lb·ft) is used in the US and UK, particularly for engine and fastener specifications. The conversion is: 1 lb·ft = 1.35582 Nm. European car specs list torque in Nm; American specs typically use lb·ft.
Torque in automotive engineering
A typical family car produces 150–300 Nm (110–220 lb·ft). A performance car: 400–600 Nm. A large truck or diesel engine: 1,000–2,000 Nm. Electric vehicles often produce peak torque instantly from 0 RPM, which is why they feel so responsive.
Torque in tools and fasteners
Torque wrenches are used to tighten bolts to precise specifications — typically in Nm or lb·ft. Over-tightening can strip threads or warp components. Cylinder head bolts: 80–120 Nm. Wheel lug nuts: 100–130 Nm. Always consult the manufacturer's torque spec.
