Moment of Force Converter

About Moment of Force Conversion

Moment of force, commonly known as torque, is a measure of the rotational force applied to an object. It is calculated as the product of the force and the perpendicular distance from the axis of rotation to the line of action of the force.

Common Moment of Force 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 kilonewton meter (kN·m) = 1000 newton meter (N·m)
• 1 pound-force foot (lbf·ft) = 1.3558179 newton meter (N·m)
• 1 pound-force inch (lbf·in) = 0.1129848 newton meter (N·m)
• 1 kilogram-force meter (kgf·m) = 9.80665 newton meter (N·m)

Applications of Moment of Force

Moment of force or torque is a fundamental concept in many engineering applications:

• Mechanical engineering (fastener tightening specifications)
• Automotive engineering (engine torque, wheel lug nut tightening)
• Structural engineering (beam analysis and design)
• Robotics and automation (servo motor control)
• Aerospace engineering (control surface design)
• Manufacturing (tool calibration and quality control)
• Sports equipment design (golf clubs, tennis rackets)

Calculating Moment of Force

The moment of force (τ) is mathematically defined as:

τ = r × F

Where:

• τ (tau) is the moment of force or torque
• r is the position vector (perpendicular distance from the axis of rotation)
• F is the applied force
• × indicates the cross product of vectors

For the simple case where the force is perpendicular to the lever arm, the magnitude of the torque can be calculated as:

τ = r × F = r·F·sin(θ)

Where θ is the angle between the force vector and the lever arm. When the force is perpendicular to the lever arm, sin(θ) = 1, so τ = r·F.

Our moment of force converter provides accurate conversions between all these units, making it easy to translate between different measurement systems for engineering calculations, mechanical design, and maintenance applications.
