About Atmosphere and Bar
Detailed information about both units of measurement.
Atmosphere
- Definition
- Standard atmospheric pressure at sea level, equal to 101,325 pascals.
- SI / Standard Information
- Defined as exactly 101,325 Pa. The atmosphere is a convenient reference unit for pressure in chemistry, physics, and diving.
- Approximate Comparison
- One atmosphere is the average pressure exerted by Earth's atmosphere at sea level.
- Practical Applications
-
- Chemistry and gas law calculations
- Scuba diving decompression tables
- Deep-sea and high-altitude research
- Vacuum system comparison
- Real-World Examples
-
- 1 atm is the pressure at sea level
- At 10 meters underwater, pressure is about 2 atm
- Mount Everest summit pressure is about 0.33 atm
Bar
- Definition
- A metric unit of pressure equal to 100,000 pascals. Slightly less than standard atmospheric pressure.
- SI / Standard Information
- Defined as 100,000 Pa (100 kPa). 1 bar ≈ 0.987 atm. Widely used in European engineering, diving, and automotive contexts.
- Approximate Comparison
- One bar is slightly less than one atmosphere of pressure. 1 bar = 14.5 PSI.
- Practical Applications
-
- European tire pressure measurement
- Scuba diving depth measurement
- Industrial compressed air systems
- European weather (millibar = hPa)
- Real-World Examples
-
- Car tire pressure is about 2.0-2.5 bar
- Scuba tanks are filled to about 200-300 bar
- Standard atmospheric pressure is 1.013 bar
