What is the definition of a bar?

A bar is a pressure unit equal to 100,000 pascals, measuring force per unit area and slightly less than standard atmospheric pressure.

Why use centimeter mercury (0°C) as a pressure unit?

Centimeter mercury (0°C) represents the pressure exerted by a mercury column at 0°C under standard gravity and is used for manometric readings and calibration.

In which fields is this bar to centimeter mercury conversion commonly applied?

It is widely applied in meteorology, various engineering disciplines, laboratory research, and industrial equipment calibration.

Tips & Best Practices

Use this tool when precise conversion between bar and centimeter mercury (0°C) is required for scientific or engineering accuracy.
Verify that ambient conditions match the standard definitions to minimize discrepancies in mercury-based units.
Be aware of the limitations of non-SI units and consider using pascals for consistency if possible.

Limitations

The bar is not an SI base unit and can be less precise than some SI units.
Centimeter mercury (0°C) depends on mercury's properties at 0°C and standard gravity, which may cause minor variations.
Mercury-based pressure units are less favored due to mercury toxicity concerns and the preference toward SI units like pascals.
