Convert attopascal to centimeter mercury (0°C)
Please provide values below to convert attopascal [aPa] to centimeter mercury (0°C) [cmHg], or Convert centimeter mercury (0°C) to attopascal.
1 aPa = 7.5006e-22 cmHg. To convert attopascal to centimeter mercury (0°C), multiply the value by 7.5006e-22; to go the other way, divide by it (1 cmHg = 1.3332e+21 aPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aPa = 7.5006e-22 cmHg
- 1 cmHg = 1.3332e+21 aPa
- 10 aPa = 7.5006e-21 cmHg
- 100 aPa = 7.5006e-20 cmHg
How to Convert Attopascal to Centimeter Mercury (0°c)
1 aPa = 7.50061578180415e-22 cmHg

Attopascal
The attopascal (aPa) is a unit of pressure equal to 10^-18 pascals, representing an extremely small pressure measurement.
History/Origin
The attopascal was introduced as part of the SI prefixes to denote very small quantities of pressure, but it is rarely used in practical applications due to its minuscule magnitude.
Current Use
The attopascal is primarily used in scientific research and theoretical contexts where extremely small pressure differences are relevant, although it remains largely a conceptual unit.
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.
