About Torque Conversion

Torque is a measure of the rotational force applied to an object. It is the product of the force applied and the perpendicular distance from the point of application to the axis of rotation.

Common Torque Conversions

  • 1 newton meter (N·m) = 0.7375621 pound-force foot (lbf·ft)
  • 1 newton meter (N·m) = 8.8507 pound-force inch (lbf·in)
  • 1 newton meter (N·m) = 0.101972 kilogram-force meter (kgf·m)
  • 1 newton meter (N·m) = 100 newton centimeter (N·cm)
  • 1 pound-force foot (lbf·ft) = 1.3558179 newton meter (N·m)
  • 1 kilogram-force meter (kgf·m) = 9.80665 newton meter (N·m)

Applications of Torque

Torque is a fundamental concept in many engineering and mechanical applications:

  • Automotive engineering (engine specifications, bolt tightening)
  • Manufacturing (proper assembly of components)
  • Mechanical engineering (design of rotational systems)
  • Construction (heavy equipment operation)
  • Robotics (motor control and precise movements)
  • Tool design and usage (wrenches, screwdrivers)

Understanding Torque

Torque can be visualized as the "twisting force" that causes rotation. When you use a wrench to tighten a bolt, the force you apply to the end of the wrench multiplied by the length of the wrench handle equals the torque applied to the bolt.

The magnitude of torque (τ) can be calculated as:

τ = F × r × sin(θ)

Where:

  • F is the applied force
  • r is the distance from the axis of rotation
  • θ is the angle between the force vector and the lever arm

When the force is applied perpendicular to the lever arm (θ = 90°), the formula simplifies to τ = F × r, which gives the maximum torque for a given force and distance.

Our torque converter provides accurate conversions between all these units, making it easy to translate between different measurement systems for engineering calculations, vehicle specifications, and tool applications.
