Torque Converter

Convert torque between newton metres and pound-feet

All conversions use newton metres (N·m) as a canonical intermediate value. 1 lb·ft = 1.3558179483314004 N·m. Results maintain full floating-point precision internally and are formatted for readability.

Units supported

• Newton metres (N·m) — the SI unit, used in European vehicle specifications and workshop torque settings.
• Pound-feet (lb·ft) — the imperial unit, used in UK and US vehicle specifications. Sometimes written ft-lb; the quantity is the same.

Reference values

• 400 N·m = 295.0 lb·ft
• 100 lb·ft = 135.6 N·m
• A typical car wheel-nut torque: 100–140 N·m (74–103 lb·ft)
• A typical diesel family car: 300–400 N·m
• A typical high-torque EV: 400–700 N·m

Torque figures quoted for engines are peak values; the torque you feel depends on gearing as well as the engine’s output.
