What Is This Tool?

This tool converts density measurements from pound per cubic inch (lb/in^3), an imperial unit often used in US engineering contexts, to kilogram per cubic meter (kg/m^3), the SI derived unit commonly used in scientific and engineering calculations worldwide.

How to Use This Tool?

  • Enter the density value in pound per cubic inch (lb/in^3).
  • Select pound/cubic inch as the input unit and kilogram/cubic meter as the output unit.
  • Click the convert button to get the equivalent density in kg/m^3.
  • Review the converted result for use in your calculations or documentation.

Key Features

  • Converts density units from pound/cubic inch to kilogram/cubic meter accurately.
  • Supports engineering and scientific usage for materials and fluid density.
  • Ideal for translating data from imperial to metric systems.
  • Easy-to-use interface for quick conversions.
  • Useful for aerospace, automotive, manufacturing, and material science fields.

Examples

  • Convert 2 lb/in^3 to kg/m^3: 2 × 27679.904710191 = 55359.81 kg/m^3
  • Convert 0.5 lb/in^3 to kg/m^3: 0.5 × 27679.904710191 = 13839.95 kg/m^3

Common Use Cases

  • Specifying densities of metals and alloys in engineering drawings with inch-based dimensions.
  • Calculating mass of small parts or castings when volume is in cubic inches.
  • Ballistics and projectile design involving pounds and cubic inches.
  • Performing fluid mechanics and buoyancy calculations with standard SI units.
  • Aerodynamics and HVAC design where air density is a consideration.
  • Material selection and structural engineering using consistent SI density units.

Tips & Best Practices

  • Ensure correct input unit selection to avoid inaccurate conversions.
  • Use the SI unit results for scientific or international engineering standards.
  • Account for possible rounding when dealing with very small or very large densities.
  • Keep consistent units across calculations for material properties and design specs.

Limitations

  • Pound/cubic inch is mainly suited for small volume, high density values.
  • Careful handling of significant figures is necessary especially in ballistics and material property applications.
  • Conversions of extreme values may be affected by rounding or precision issues.

Frequently Asked Questions

What is pound per cubic inch used for?
It is a density unit used mainly in US engineering and manufacturing to express mass per volume in pounds per cubic inch, often for metals, alloys, and small parts.

Why convert pound/cubic inch to kilogram/cubic meter?
