Torque Converter
Last updated: June 19, 2026
A torque converter is a mechanical measurement utility that translates rotational force values between different unit systems. The converter supports conversions across newton-meters (N·m), kilonewton-meters (kN·m), pound-feet (lb·ft), pound-inches (lb·in), kilogram-force meters, and ounce-inches. It applies standard physical conversion factors to ensure exact accuracy. Mechanical engineering students, automotive mechanics, manufacturers, and technicians use this tool to standardize rotational torque specifications for engines, fasteners, and machinery.
Pick a 'from' unit and a 'to' unit, enter a torque value, and the converter returns all common torque units. Useful for service manuals, fastener specs, and physics homework.
Quick Answer
Convert torque values between metric and imperial units. Enter your torque value and select units to calculate conversions across newton-meters and pound-feet.
Decimals and negative values are fine. · e.g. 100
Internal base unit is N·m. Each conversion goes through N·m, so accuracy is consistent across pairs.
Newton meter → Pound foot
73.7562 lb·ft
100 (from) = 73.7562 (to)
1 lb·ft ≈ 1.3558 N·m; 1 lb·in ≈ 0.113 N·m; 1 oz·in ≈ 0.00706 N·m; 1 kgf·m = 9.80665 N·m. Use lb·in or oz·in for small fasteners and electronics; use N·m or lb·ft for automotive work.
Examples
100 N·m
≈ 73.76 lb·ft; 885.07 lb·in
50 lb·ft
≈ 67.79 N·m; 600 lb·in
10 oz·in
≈ 0.0706 N·m; 0.625 lb·in
1 kgf·m
= 9.80665 N·m ≈ 7.233 lb·ft
How it works
Each torque unit is defined by its size in newton meters. The converter multiplies the input by the source factor, then divides by the target factor.
Imperial · 1 lb·ft ≈ 1.3558 N·m; 1 lb·in ≈ 0.113 N·m
Small fastener · 1 oz·in ≈ 0.00706 N·m
Metric force-meter · 1 kgf·m = 9.80665 N·m

Frequently asked questions
Torque is the rotational equivalent of force: how hard you twist something around an axis. The SI unit is the newton meter (N·m), the product of force (N) and lever arm (m).
Mathematically yes, but the contexts differ. A joule measures energy or work; a newton meter measures torque. Convention keeps them separate to avoid confusion (you would not say a bolt is tightened to 50 joules).
1 N·m ≈ 0.7376 lb·ft. So 100 N·m ≈ 73.76 lb·ft. The calculator handles all the common pairs, including pound-inch and ounce-inch for small fasteners.
Small fastener specs (electronics, eyeglasses, fine instruments) are typically in oz·in or lb·in. Pound-feet are typical for automotive and structural torque values. The calculator covers all of them.
