Density Conversions: Understanding Material Properties

Density is a fundamental property of materials, defined as mass per unit volume. Here's a guide to common density conversions:

Common Conversions

• 1 gram per cubic centimeter (g/cm³) = 1,000 kilograms per cubic meter (kg/m³)
• 1 gram per cubic centimeter (g/cm³) = 62.428 pounds per cubic foot (lb/ft³)
• 1 pound per cubic foot (lb/ft³) = 0.01602 grams per cubic centimeter (g/cm³)
• 1 pound per cubic foot (lb/ft³) = 16.02 kilograms per cubic meter (kg/m³)
• 1 pound per gallon (US) (lb/gal) = 0.1198 grams per cubic centimeter (g/cm³)
• 1 gram per cubic centimeter (g/cm³) = 8.345 pounds per gallon (US) (lb/gal)

Common Material Densities

• Water: 1.0 g/cm³ (at 4°C)
• Ice: 0.917 g/cm³
• Air: 0.001225 g/cm³ (at sea level, 15°C)
• Aluminum: 2.7 g/cm³
• Iron: 7.87 g/cm³
• Gold: 19.3 g/cm³

Density is useful for identifying materials, calculating buoyancy, and determining the mass of a known volume of material.
