Why do I need to convert from atm to centimeter mercury (0°C)?

This conversion helps relate atmospheric pressures to mercury column readings commonly used in labs and engineering, enabling accurate calibration and measurement interpretation.

Is the conversion dependent on temperature or gravity?

Yes, the conversion assumes mercury at 0 °C under standard gravity; deviations affect the accuracy of the result.

Why are mercury-based pressure units less common now?

Due to toxicity and environmental concerns, mercury units are being phased out in some fields despite their historical and experimental uses.
