Common Use Cases for Torque Converter
Automotive Repair & Maintenance
Torque specifications for lug nuts, cylinder head bolts, and spark plugs are often listed in N·m in European manuals and ft·lbf in US manuals. Use our torque converter to match your torque wrench setting to the spec in any unit.
Mechanical Engineering & Design
Engineers designing fastener joints, gearboxes, and rotating assemblies frequently need to convert torque values between SI units (N·m, kN·m) and imperial units (ft·lbf, in·lbf). Our torque converter handles all 15 units with full precision.
Engine & Powertrain Specifications
Engine torque output is published in N·m in most countries and ft·lbf in the United States. When comparing vehicles or reading international datasheets, our torque converter lets you instantly translate any engine torque figure.
Cycling & Sports Equipment
Bicycle component torque specs — stem bolts, brake calipers, bottom brackets — are typically given in N·m. Mechanics using older tools calibrated in in·lbf or kgf·cm can use our torque converter to get the exact equivalent value.
Physics & Scientific Research
Researchers working with rotational dynamics, moment of force, and torsion experiments need precise torque conversions between SI and CGS units (dyn·cm, dyn·m). Our torque converter supports all standard scientific units.
Industrial & Manufacturing
Assembly lines and quality control processes often specify torque in kgf·m or kgf·cm for legacy equipment while modern standards use N·m. Our torque converter bridges the gap between old and new specifications instantly.
Understanding Torque Conversion
What is Torque?
Torque (also called moment of force or rotational force) is the tendency of a force to rotate an object about an axis. It is calculated as the product of the applied force and the perpendicular distance from the axis of rotation to the line of action of the force: τ = F × r. The SI unit of torque is the Newton-metre (N·m), while the most common imperial unit is the foot-pound force (ft·lbf). Our torque converter supports 15 units across SI, imperial, and CGS systems.

Key Torque Units Explained
- Newton-metre (N·m): The SI unit of torque. One N·m is the torque produced by a force of 1 Newton acting at a perpendicular distance of 1 metre from the axis. Used universally in engineering, automotive, and scientific contexts worldwide.
- Foot-pound force (ft·lbf): The primary imperial torque unit used in the United States. One ft·lbf equals approximately 1.3558 N·m. Engine torque, lug nut specs, and torque wrench settings in the US are commonly expressed in ft·lbf.
- Inch-pound force (in·lbf): Used for smaller fasteners and precision applications. One in·lbf = 1/12 ft·lbf ≈ 0.1130 N·m. Common in electronics assembly, bicycle components, and small engine work where fine torque control is required.
- Kilogram-force metre (kgf·m): A gravitational metric unit still used in some legacy specifications and older Japanese and European manuals. One kgf·m ≈ 9.8067 N·m. Often seen in older automotive and industrial documentation.
Torque vs. Work — Same Units, Different Concepts: Both torque and work (energy) are expressed in N·m (or equivalently, Joules for energy). However, they are fundamentally different physical quantities. Work is a scalar quantity representing energy transferred, while torque is a vector quantity representing rotational force. The N·m unit for torque is kept distinct from the Joule (J) to avoid confusion — torque is never expressed in Joules. When using our torque converter, all values represent rotational force, not energy.

Frequently Asked Questions About Torque Converter
A torque converter is a tool that transforms a torque value from one unit to an equivalent value in another unit. Our torque converter supports 15 units including N·m, ft·lbf, in·lbf, kgf·m, kgf·cm, ozf·in, dyn·cm, and more — all processed instantly in your browser with no signup required.
To convert Newton-metres to foot-pound force, multiply by 0.737562. For example, 100 N·m = 73.756 ft·lbf. Our torque converter applies this factor automatically — just select N·m as the source, ft·lbf as the target, enter your value, and click Convert.
To convert foot-pound force to Newton-metres, multiply by 1.355818. For example, 100 ft·lbf = 135.58 N·m. Use the swap button in our torque converter to instantly reverse the conversion direction without re-entering your value.
Both N·m and kgf·m are metric torque units, but kgf·m uses the kilogram-force (a gravitational unit) rather than the Newton (an SI force unit). One kgf·m equals exactly 9.80665 N·m, since 1 kgf = 9.80665 N. The N·m is the modern SI standard; kgf·m appears in older European and Japanese specifications.
Both are imperial torque units. One ft·lbf = 12 in·lbf, since a foot is 12 inches. Inch-pound force (in·lbf) is used for smaller fasteners and precision work (e.g., bicycle components, electronics), while foot-pound force (ft·lbf) is used for larger applications like engine bolts and lug nuts.

Torque and work both use the unit N·m, but they are different physical quantities. Work (energy) is a scalar measured in Joules (J = N·m), while torque is a vector representing rotational force. To avoid confusion, torque is always written as N·m and never as Joules. Our torque converter deals exclusively with rotational force, not energy.
Automotive torque specs use ft·lbf in the United States and N·m in most other countries. Older Japanese and European manuals sometimes use kgf·m. Small fasteners like spark plugs may be specified in in·lbf or N·m. Our torque converter handles all these units so you can match any spec to your torque wrench.
