What is the Torque Converter?

Torque (or moment) is a rotational force that causes an object to spin or turn around an axis, measured in units like Newton-metres (N·m) and pound-feet (lb-ft). Different industries and regions use different torque units: automotive specs often list lb-ft, mechanical engineering uses N·m, and Japanese tooling may specify kg·cm. A torque converter bridges these standards, letting you convert between all common units instantly.

How it works

The converter multiplies your input value by the appropriate conversion factor based on the units you're translating between. For example, to convert N·m to lb-ft, the tool multiplies by approximately 0.7376; to convert lb-ft to N·m, it multiplies by 1.3558. Simply enter your torque value, select the starting unit, choose your target unit, and the result updates immediately.

Output = Input × Conversion Factor

The conversion factor is a fixed multiplier unique to each pair of units. For instance: 1 N·m = 0.7376 lb-ft; 1 lb-ft = 1.3558 N·m; 1 N·m = 10.197 kg·cm; 1 kg·cm = 0.0981 N·m.

How to use the Torque Converter

  1. Enter the torque value you want to convert in the input field.
  2. Select the unit of your input value from the 'From' dropdown (e.g., lb-ft, N·m, kg·cm, oz·in).
  3. Select the unit you want to convert to from the 'To' dropdown.
  4. The converter calculates and displays the result instantly.
  5. Copy the result or adjust your input to compare multiple conversions.
  6. Use the result in your technical specification, assembly manual, or fastening procedure.

Benefits

  • Eliminates guesswork when working across international specs and metric vs. imperial standards.
  • Prevents costly mistakes like over-tightening fasteners due to unit confusion.
  • Saves time during automotive repair, machinery assembly, and engineering design.
  • Ensures fasteners are torqued to exact manufacturer specs, improving safety and reliability.
  • Supports multiple torque units (N·m, lb-ft, lb·in, kg·cm, oz·in) in one tool.

Tips & common mistakes

Common mistakes

  • Confusing torque with power: torque is rotational force, power is the rate of doing work. This tool converts torque, not horsepower or watts.
  • Forgetting to apply the torque spec for the specific fastener material and thread size; conversion gets the unit right, but the spec must match your application.
  • Mixing up lb-ft and lb·in: 1 lb-ft = 12 lb·in, a critical difference when tightening small fasteners.

Tips

  • Bookmark or screenshot critical torque specs for your car, motorcycle, or equipment so you can quickly verify the right unit before tightening.
  • Use a torque wrench calibrated to the units your manual specifies; if your manual lists lb-ft and your wrench reads N·m, convert before applying.
  • For safety-critical fasteners (engine heads, brake components, wheel lugs), always double-check the spec and converted value—never guess.

Frequently asked questions

What's the difference between N·m and lb-ft?

Both measure torque (rotational force). 1 lb-ft = 1.3558 N·m. Newton-metres are used globally in engineering and automotive specs; pound-feet are common in North America. The tool converts between them instantly.

Can I use this converter for power (horsepower, watts)?

No. This tool converts torque only. Power depends on both torque and rotational speed (RPM). To convert power units, use a separate power converter.

Why does my car manual list torque in lb-ft but my wrench is metric?

Regional standards: many older or North American specs use imperial units, while modern and imported vehicles often use metric. Use this converter to translate the spec to match your wrench's scale.

Is 50 N·m the same as 50 lb-ft?

No. 50 N·m equals about 36.88 lb-ft, and 50 lb-ft equals about 67.79 N·m. Always convert to confirm the actual value.

What is kg·cm used for?

Kilogram-centimetres are common in Japanese automotive and industrial tool specifications. 1 kg·cm = 0.0981 N·m, a much smaller unit than N·m or lb-ft.

Can I convert oz·in to other units with this tool?

Yes. Ounce-inches (oz·in) measure small torques for delicate fasteners and instruments. 1 oz·in = 0.00707 N·m or 0.00522 lb-ft. This converter handles all common torque units.
