What does 1 decipascal represent?

1 decipascal is one tenth of a pascal, representing a small pressure unit used for fine pressure measurements.

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

Centimeter mercury (0°C) is used in laboratory manometers and barometers to express pressure based on mercury column height under standard conditions.

Can this converter be used for all pressure ranges?

No, it is optimized for very small pressure values measured in decipascal and may not be suitable for larger pressure ranges.
