How convert pounds to ft3 (cubic feet) and vice versa?

Use the following formulas to calculate:

1) Volume = Weight / Density
2) Weight = Volume * Density
3) Density = Weight / Volume

Reference data:

Density of water = 62.42 lb/ft3
Density of steel = 486.9 lb/ft3
Density of concrete = 87.39 ... 156.05 lb/ft3
Density of sand = 87.39 ... 106.12 lb/ft3
Density of paint = 56.17 ... 98.88 lb/ft3
Density of milk = 64.19 ... 64.56 lb/ft3
Density of oil = 46.87 ... 62.19 lb/ft3
Density of air = 0.0765 lb/ft3

Weight is a characteristic of the body, which is a measure of the gravitational interaction with other bodies.

Volume is a quantitative characteristic of the space occupied by a body or substance.

Density is a measure of mass per unit of volume.

Weight and volume depend on temperature, pressure and composition due to density changes.
