Convert centimeter mercury (0°C) to petapascal
Please provide values below to convert centimeter mercury (0°C) [cmHg] to petapascal [PPa], or Convert petapascal to centimeter mercury (0°C).
1 cmHg = 1.3332e-12 PPa. To convert centimeter mercury (0°C) to petapascal, multiply the value by 1.3332e-12; to go the other way, divide by it (1 PPa = 750061578180 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-12 PPa
- 1 PPa = 750061578180 cmHg
- 10 cmHg = 1.3332e-11 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.
Petapascal
A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.
History/Origin
The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.
Current Use
Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
