Accuracy depends on mercury temperature being exactly 0 °C and standard gravity
-
Centimeter mercury units are uncommon outside specific technical fields
-
Conversion may not reflect real-world variations in conditions affecting pressure measurement
Frequently Asked Questions
-
What does 1 centimeter mercury (0°C) represent?
-
It is the pressure exerted by a 1 cm column of mercury at 0 °C under standard gravity, approximately equal to 1,333.2239 pascals.
-
Why convert to dekapascal (daPa)?
-
Dekapascal is an SI-derived unit, simplifying pressure comparisons and calibrations, especially in audiology, HVAC, and laboratory settings.
-
Where is this conversion most commonly applied?
-
In laboratory instrumentation, audiology clinics, HVAC diagnostics, cleanroom pressure monitoring, and calibration of low-pressure sensors.
Key Terminology
