Convert attopascal to millimeter mercury (0°C)
Please provide values below to convert attopascal [aPa] to millimeter mercury (0°C) [mmHg], or Convert millimeter mercury (0°C) to attopascal.
1 aPa = 7.5006e-21 mmHg. To convert attopascal to millimeter mercury (0°C), multiply the value by 7.5006e-21; to go the other way, divide by it (1 mmHg = 1.3332e+20 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-21 mmHg
- 1 mmHg = 1.3332e+20 aPa
- 10 aPa = 7.5006e-20 mmHg
- 100 aPa = 7.5006e-19 mmHg
How to Convert Attopascal to Millimeter Mercury (0°c)
1 aPa = 7.50061578180415e-21 mmHg
Example: convert 15 aPa to mmHg:
15 aPa = 15 × 7.50061578180415e-21 mmHg = 1.12509236727062e-19 mmHg

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.
Millimeter Mercury (0°c)
Millimeter mercury (0°C), abbreviated as mmHg, is a unit of pressure measurement based on the height of a column of mercury in millimeters at 0°C under standard gravity.
History/Origin
The mmHg originated from the use of mercury barometers in the 17th century to measure atmospheric pressure. It became a standard unit in meteorology and medicine for measuring blood pressure and other pressure-related phenomena.
Current Use
Today, mmHg is primarily used in medicine to measure blood pressure and in meteorology for atmospheric pressure readings. It is also used in various scientific and industrial applications where precise pressure measurements are required.
