What are Water and Mercury

Definition of Water

Water, a transparent fluid, is the most abundant substance on Earth, vital for all known forms of life. At 4 degrees Celsius, water reaches its maximum density, and it's commonly used as a reference in the centimeter water column (cmH2O), a unit to measure pressure.

Definition of Mercury

Mercury, a metallic element with a silvery appearance, is the only metal that is liquid at standard conditions for temperature and pressure. Often used in thermometers, barometers, and other scientific apparatus, it is also employed as a standard unit of pressure represented as centimeter mercury (cmHg) at 0 degrees Celsius.

Water to Mercury Conversion Table

Centimeter Water (cmH2O) Centimeter Mercury (cmHg)
1 cmH2O 0.07355 cmHg
2 cmH2O 0.1471 cmHg
3 cmH2O 0.22065 cmHg
4 cmH2O 0.2942 cmHg
5 cmH2O 0.36775 cmHg
6 cmH2O 0.4413 cmHg
7 cmH2O 0.51485 cmHg
8 cmH2O 0.5884 cmHg
9 cmH2O 0.66195 cmHg
10 cmH2O 0.7355 cmHg

Conversion of Water to Mercury

1 cmH2O = 0.07355 cmHg
1 cmHg = 13.5951 cmH2O

Example 1:
convert 10 cmH2O to cmHg:
10 cmH2O = 10 × 0.07355 cmHg = 0.7355 cmHg

Example 2:
convert 5 cmH2O to cmHg:
5 cmH2O = 5 × 0.07355 cmHg = 0.36775 cmHg

History of Water and Mercury

A brief history of the cmH2O to cmHg conversion reflects the evolution of pressure measurement. Initially using water's weight to indicate pressure, the discovery of mercury's higher density led to its use for more accurate readings in scientific research and industry applications.
