Why is the temperature reference important in this conversion?

The temperature affects the density of water and mercury columns, so specifying 4°C for inch water and 0°C for centimeter mercury ensures consistent hydrostatic pressure values.

Can I use this conversion for high-pressure measurements?

No, inch water is intended for very low-pressure readings and may not be accurate for high-pressure measurements.

What applications use centimeter mercury as a pressure unit?

Centimeter mercury is commonly used in laboratory manometers, barometers, sensor calibration, and physics or engineering pressure calculations.
