What is a Foot-Pound (ft lb)?

foot-pound is a unit of torque in the imperial system. It measures the rotational force applied at a distance of one foot.

Key Facts About Foot-Pounds

  • Exact value: 1 ft lb = 1.35582 Nm.
  • Relationship: Defined as 1 pound-force applied one foot from the pivot.
  • Abbreviation: ft lb or lb·ft.
  • Usage: Automotive torque specifications, mechanical tools, physics problems.

What is a Newton-Meter (Nm)?

Newton-meter is the SI unit of torque in the metric system. It represents the force of one newton applied at a one-meter distance.

Key Facts About Newton-Meters

  • Exact value: 1 Nm = 0.73756 ft lb.
  • Relationship: 1 Nm = 1 joule (in work-energy context).
  • Abbreviation: Nm.
  • Usage: Engineering, physics, automotive torque ratings, construction.
