Density is mass per volume, so each unit is a mass unit divided by a volume unit, held here as kilograms per cubic metre. The metric units differ by powers of 1,000 (1 g/cm³ = 1 g/mL = 1 kg/L = 1,000 kg/m³), and the imperial ones follow from the exact pound and foot: 1 lb/ft³ = 16.0185 kg/m³.
The default converts 1 g/cm³, close to the density of water, to 62.428 lb/ft³. Engineers use lb/ft³ (pcf) for soils and concrete, drillers use lb/gal (ppg) for drilling mud, and materials data sheets use g/cm³.
Density changes with temperature, and the converter only changes units. Pure water is densest near 4 °C at 999.97 kg/m³ and is 998.2 kg/m³ at 20 °C, so “1 g/cm³ for water” is right to within 0.2%.

ਸਵਾਲ
How do I convert g/cm³ to kg/m³?
Multiply by 1,000. A cubic metre holds 10⁶ cubic centimetres and a kilogram is 1,000 grams, so 1 g/cm³ = 1,000 kg/m³. Aluminium at 2.70 g/cm³ is 2,700 kg/m³, and steel at about 7.85 g/cm³ is 7,850 kg/m³. g/mL and kg/L are the same size as g/cm³.
What is specific gravity?
The ratio of a substance's density to the density of water, so it has no unit. Referenced to water at 4 °C (999.97 kg/m³), specific gravity equals the density in g/cm³ to within 0.003%: a liquid of 0.80 g/cm³ has a specific gravity of 0.80. Other references, such as water at 60 °F, change the fourth significant digit.
How do I convert lb/ft³ to kg/m³?
Multiply by 16.0185. A pound is 0.45359237 kg and a cubic foot 0.028316846592 m³, both exact, so 1 lb/ft³ = 16.01846337 kg/m³. Normal-weight concrete at about 150 lb/ft³ is about 2,400 kg/m³, and 1,000 kg/m³ is 62.43 lb/ft³.
What does ppg mean for drilling mud?
Pounds per US gallon, the density unit of oilfield drilling fluids. 1 lb/gal is 119.826 kg/m³, so fresh water at 20 °C is 8.33 ppg and a 12 ppg mud is 1,438 kg/m³, or 1.44 g/cm³. Mud weight sets the pressure the fluid column exerts at the bottom of the well.
Is the density of water exactly 1 g/cm³?
No, but close. Pure water peaks at 999.97 kg/m³ near 4 °C and is 998.2 kg/m³ at 20 °C. The gram was first defined in 1795 as the mass of 1 cm³ of water, and from 1901 to 1964 the litre was defined as the volume of 1 kg of water, which is why the numbers nearly coincide.
