Convert bar to Standard atmosphere
Please provide values below to convert bar [bar] to Standard atmosphere [atm], or Convert Standard atmosphere to bar.
1 bar = 0.986923266716 atm. To convert bar to Standard atmosphere, multiply the value by 0.986923266716; to go the other way, divide by it (1 atm = 1.01325 bar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 bar = 0.986923266716 atm
- 1 atm = 1.01325 bar
- 10 bar = 9.86923266716 atm
- 100 bar = 98.6923266716 atm
How to Convert Bar to Standard Atmosphere
1 bar = 0.986923266716013 atm
Example: convert 15 bar to atm:
15 bar = 15 × 0.986923266716013 atm = 14.8038490007402 atm

Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
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.
