Please provide values below to convert pascal [Pa] to centimeter mercury (0°C) [cmHg], or Convert centimeter mercury (0°C) to pascal.
How to Convert Pascal to Centimeter Mercury (0°c)
1 Pa = 0.000750061578180415 cmHg
Example: convert 15 Pa to cmHg:
15 Pa = 15 × 0.000750061578180415 cmHg = 0.0112509236727062 cmHg
Pascal to Centimeter Mercury (0°c) Conversion Table
| pascal | centimeter mercury (0°C) |

Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
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.
