Convert Standard atmosphere to hectopascal
Please provide values below to convert Standard atmosphere [atm] to hectopascal [hPa], or Convert hectopascal to Standard atmosphere.
1 atm = 1013.25 hPa. To convert Standard atmosphere to hectopascal, multiply the value by 1013.25; to go the other way, divide by it (1 hPa = 0.000986923266716 atm). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 atm = 1013.25 hPa
- 1 hPa = 0.000986923266716 atm
- 10 atm = 10132.5 hPa
- 100 atm = 101325 hPa
How to Convert Standard Atmosphere to Hectopascal
1 atm = 1013.25 hPa
Example: convert 15 atm to hPa:
15 atm = 15 × 1013.25 hPa = 15198.75 hPa

Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
