## Density

Density
Density of a system is the mass of the unit
volume of the system. Note that the density is reciprocal of
specific volume i.e.

The density of gases and vapors is dependent on temperature and pressure while density of most solids
and liquids is dependent only on temperature with good precision for many engineering applications.

The SI unit of density is **kg/m** (kilogram per cubic meter). Other units are:

- 1 t/m = 1000 kg/m
- 1 lbm/ft = 16.018 kg/m
- 1 lbm/(U.K.gal)= 99.776 kg/m
- 1 lbm/(U.S.gal)= 119.83 kg/m
- 1 slug/ft = 515.38 kg/m
- 1 g/cm = 1000 kg/m
- 1 U.K.ton/yd = 1328.94 kg/m
- 1 U.S.ton/yd = 1186.5 kg/m
