Frequently Asked Questions
-
What is a centimeter water (4°C)?
-
It is a pressure unit equal to the pressure exerted by a 1 cm column of water at 4°C, often used for small pressure measurements in medical and laboratory contexts.
-
What does millimeter mercury (0°C) measure?
-
Millimeter mercury (0°C) is a pressure unit representing the pressure from a 1 mm column of mercury at 0°C, commonly used in clinical and engineering measurements.
-
Why convert centimeter water to millimeter mercury?
-
Converting to millimeter mercury standardizes small pressure readings into a widely used unit facilitating clinical reporting and laboratory analysis.
