About Torque (Newton-metres)

Converts torque values to Newton-metres (N·m), the SI unit of rotational force. Used to size motors, fasteners, and shafts.

How It Works

Torque = Force × Perpendicular distance. 1 N·m = 1 J of energy per radian of rotation. To convert: ft·lb × 1.35582 = N·m; in·lb × 0.11298 = N·m.

Reference Values & Examples

  • A car wheel nut torqued to 100 N·m ≈ 74 ft·lb
  • Engine rated at 400 N·m ≈ 295 ft·lb peak torque
  • 10 in·lb ≈ 1.13 N·m for small fasteners

Common Applications

  • Machine component design and selection
  • Material stress and fatigue analysis
  • Structural integrity verification
  • Manufacturing quality control
  • Mechanical engineering coursework and licensing exams

Did You Know?

The safety factor concept dates to Isambard Kingdom Brunel, who routinely over-engineered Victorian bridges by 3–4× to account for material variability — a principle still used in codes like ASME and Eurocode today.

Common Mistake

Confusing torque (N·m) with energy (also N·m = joules). Torque and energy share units but are physically different — torque acts around an axis, energy acts through a distance.
