Densities of Common Substances
Deity is defined as mass divided by volume, or mass per unit volume. The deity in kilograms per cubic meter can be obtained by multiplying the table values by 1000. The deities of most of the pure...

Viscosity of Liquids and Gases
Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. More commonly used is the dyne sec/cm2 which is called Poise. One Pa s is 10 Poise. The Poise is used in the table bec...

Compressibility of Liquids
Compressibility is the fractional change in volume per unit increase in pressure. For each atmosphere increase in pressure, the volume of water would decrease 46.4 parts per million. The compressibili...

Angular Speed of Earth
The average angular speed Wav is the average rate of change of the angular displacement.The Earth's angular velocity is cotant (or nearly cotant). Therefore we can calculate the average ang...

Volume measures
Units of capacity and volume - United States customary units The cubic inch, cubic foot and cubic yard are commonly used for measuring volume. In addition, there is one group of units for measuring...
