Converting from Centimeter of Water (cmH₂0) to Inch of Mercury (inHg) in Pressure

What is Centimeter of Water (cmH₂0)

Centimeter of Water (cmH₂0) is a unit of pressure commonly used in medical and scientific fields to measure fluid pressure. It represents the pressure exerted by a column of water that is 1 centimeter in height at standard gravity.

What is Inch of Mercury (inHg)

Inch of Mercury (inHg) is another unit of pressure that is defined as the pressure exerted by a column of mercury that is 1 inch in height at standard gravity. This unit is often used in meteorology and aviation to measure atmospheric pressure.
