What Is This Tool?

This converter allows you to change moment of inertia measurements from kilogram square millimeter (kg·mm²), a metric-derived unit, to pound square inch [lb*in^2], an Imperial/US customary unit. It helps translate design data between metric and Imperial systems for components such as shafts, rotors, and flywheels.

How to Use This Tool?

  • Enter the moment of inertia value in kilogram square millimeter.
  • Select kilogram square millimeter as the starting unit.
  • Choose pound square inch [lb*in^2] as the target unit.
  • Execute the conversion to get the result in pound square inch.

Key Features

  • Converts moment of inertia units between kilogram square millimeter and pound square inch [lb*in^2].
  • Easy to use, browser-based interface for quick conversions.
  • Supports engineering, CAD/FEA modeling, and robotics applications.
  • Provides conversion based on recognized definitions and use cases.

Examples

  • 10 Kilogram square millimeter converts to 0.034171719 Pound square inch [lb*in^2].
  • 100 Kilogram square millimeter converts to 0.34171719 Pound square inch [lb*in^2].

Common Use Cases

  • Specifying rotor or shaft inertia for small electric motors and servos in different unit systems.
  • Listing component inertia in CAD/FEA models for mechanical parts like gears and bearings.
  • Performing engineering calculations in automotive design using Imperial units.
  • Comparing flywheel or encoder-disk inertia in robotics and precision instruments.

Tips & Best Practices

  • Always confirm unit symbols and definitions before converting to avoid errors.
  • Use the tool when working across metric and Imperial measurement systems.
  • Apply the conversion carefully in design contexts where rotational inertia impacts performance.
  • Avoid mixing mass moment of inertia units with force units during calculations.

Limitations

  • Pound square inch is specifically a mass moment of inertia unit, not a force unit.
  • Mixing metric and Imperial units can cause calculation mistakes if done incorrectly.
  • The conversion assumes the pound is pound-mass (lbm), not pound-force.

Frequently Asked Questions

What does kilogram square millimeter measure?
It measures moment of inertia as mass times the square of distance, representing resistance to angular acceleration.

Can I use pound square inch for force calculations?
No, pound square inch here refers only to mass moment of inertia, not force units.

Why convert between these units?
Users convert to translate moment of inertia values between metric and Imperial systems for design and engineering that involve rotational inertia.

Key Terminology

Kilogram square millimeter (kg·mm²)
A unit measuring moment of inertia equal to mass times distance squared, derived from SI units.
Pound square inch [lb*in^2]
An Imperial unit of mass moment of inertia, being pound-mass multiplied by square inch.
Moment of inertia
A physical quantity expressing an object's resistance to angular acceleration around an axis.
