Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
