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

What is Centimeter of Water (cmH₂0)

Centimeter of Water (cmH₂0) is a unit used to measure pressure, particularly in medical and environmental fields. It represents the pressure exerted at the base of a column of water that is 1 centimeter in height.

What is Centimeter of Mercury (cmHg)

Centimeter of Mercury (cmHg) is another unit for measuring pressure, commonly used in barometers and weather instruments. It denotes the pressure needed to support a column of mercury that is 1 centimeter high under standard conditions.

Conversion Formulas

To convert from Centimeter of Water to Centimeter of Mercury, you can use the formula:

cmHg=cmH₂0×0.07355591

And to convert from Centimeter of Mercury to Centimeter of Water, use:

cmH₂0=cmHg×13.5951

Examples

1. Converting 13 cmH₂0 to cmHg:

13×0.07355591=0.9562268 cmHg

2. Converting 9 cmHg to cmH₂0:

9×13.5951=122.3559 cmH₂0

3. Conversion of 11 cmHg to cmH₂0:

11×13.5951=149.5461 cmH₂0

Conclusion

Use these conversion formulas to easily switch between Centimeter of Water and Centimeter of Mercury in pressure measurements.
