How to Convert Torque Units

To perform a conversion, look up the target unit's conversion factor relative to the base unit (newton-meter). Below are the exact mathematical formulas for the most common torque unit pairs:

Newton-meter to Pound-foot lb·ft = N·m × 0.737562149
Pound-foot to Newton-meter N·m = lb·ft × 1.355817948
Newton-meter to Pound-foot lb·ft = N·m × 0.737562149
Newton-meter to Pound-inch lb·in = N·m × 8.850745791

Every Torque Unit, Explained

Torque conversion covers 4 units. Below is a plain-English definition of each one and where you'll actually meet it in daily life.

Newton-meter (N·m)

A newton-meter is the SI unit of torque — one newton of force applied at a one-meter lever arm.

Used for: Automotive torque specs, electric-motor ratings, and mechanical engineering.

Pound-foot (lb·ft)

A pound-foot is the torque from one pound of force at a one-foot lever arm, about 1.3558 newton-meters.

Used for: Vehicle lug nuts and bolt torque specs in the US.

Pound-inch (lb·in)

A pound-inch is one-twelfth of a pound-foot, about 0.113 newton-meters.

Used for: Small fasteners, electronics assemblies, and fine torque adjustments.

Kilogram-meter (kg·m)

A kilogram-meter is a metric torque unit equal to 9.80665 newton-meters.

Used for: Older European and Asian machinery specifications.

Specialist Torque Calculators & Real-World Niche Tools

Torque represents the rotational force applied to fasteners, typically measured in foot-pounds (ft-lb), inch-pounds (in-lb), or Newton-meters (N·m). Selecting and converting the correct torque values is crucial in mechanical assembly and vehicle servicing.

An accurate torque conversion guarantees components are tightened according to tight manufacturer tolerances. Bolt torque specification calculators cross-reference fastener sizing and grades (such as Grade 5, Grade 8, or Metric 10.9) to determine safe tension levels without stripping threads. Our specialized torque calculators convert rotational forces and help mechanics apply the correct clamping pressure to engine bolts and wheel lugs.
