Torque Converter

Convert torque instantly between Newton metres (Nm), pound-feet (lb-ft), pound-inches (lb-in), and kilogram-force metres (kg·m). This free converter uses internationally recognised conversion factors and is ideal for vehicle specifications, engine tuning, motorcycles, engineering, and workshop calculations.

✔ Instant conversion • ✔ Automotive & engineering • ✔ No registration required

Tip: European manufacturers usually quote torque in Nm, while many US manufacturers use lb-ft.

What Is Torque?

Torque is a measure of rotational force produced by an engine or motor. In the automotive world it determines how strongly a vehicle accelerates, especially at lower engine speeds. Higher torque generally means stronger pulling power, making it particularly important for towing, heavy vehicles, motorcycles, and performance cars.

Units Supported by This Torque Converter

This converter supports four of the most commonly used torque units worldwide:

• Newton metres (Nm) – Standard SI unit used across Europe and most technical documentation.
• Pound-feet (lb-ft) – Commonly used in the United States, Canada, and many automotive publications.
• Pound-inches (lb-in) – Frequently used for smaller torque values, engineering, and workshop specifications.
• Kilogram-force metres (kg·m) – Still found in older workshop manuals and machinery specifications.

Official Conversion Factors

This calculator uses internationally recognised conversion constants for accurate results:

• 1 Nm = 0.737562 lb-ft
• 1 Nm = 8.85075 lb-in
• 1 Nm = 0.101972 kg·m
• 1 lb-ft = 12 lb-in

Worked Examples

Example 1 — Convert 850 Nm to lb-ft

850 Nm × 0.737562 = 627.93 lb-ft.

Example 2 — Convert 600 lb-ft to Nm

600 lb-ft × 1.35582 = 813.49 Nm.

Where Torque Conversions Are Used

Frequently Asked Questions

Why do Europe and the USA use different torque units?

Most European manufacturers use Newton metres (Nm) because it is the official SI unit. North American manufacturers often quote pound-feet (lb-ft), which remains the traditional imperial unit for automotive torque.

Which unit is more accurate?

Neither. They measure exactly the same quantity using different unit systems. This converter simply changes the units without affecting the underlying value.
