Converting from Centimeter of Mercury (cmHg) to Inch of Water (inH₂0)

What is Centimeter of Mercury (cmHg)

Centimeter of Mercury (cmHg) is a unit of pressure commonly used in the field of medicine and meteorology. It is defined as the pressure exerted by a column of mercury 1 centimeter high at standard gravity.

What is Inch of Water (inH₂0)

Inch of Water (inH₂0) is another unit of pressure, often used in HVAC systems to measure air pressure. It is defined as the pressure exerted by a column of water 1 inch high at standard gravity.
