Convert centimeter mercury (0°C) to picopascal
Please provide values below to convert centimeter mercury (0°C) [cmHg] to picopascal [pPa], or Convert picopascal to centimeter mercury (0°C).
1 cmHg = 1.3332e+15 pPa. To convert centimeter mercury (0°C) to picopascal, multiply the value by 1.3332e+15; to go the other way, divide by it (1 pPa = 7.5006e-16 cmHg). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cmHg = 1.3332e+15 pPa
- 1 pPa = 7.5006e-16 cmHg
- 10 cmHg = 1.3332e+16 pPa
- 100 cmHg = 1.3332e+17 pPa

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.
Picopascal
The picopascal (pPa) is a unit of pressure equal to 10^-12 pascals, representing an extremely small pressure measurement.
History/Origin
The picopascal was introduced as part of the SI prefixes to measure very low pressures, primarily in scientific research and specialized fields requiring high precision. Its usage has been limited due to the small magnitude of the unit.
Current Use
Currently, the picopascal is rarely used in practical applications but may be employed in scientific experiments involving ultra-low pressure measurements or in theoretical contexts where extremely small pressure values are relevant.
