Conversion Formula
The formula to convert bars to atm is: atm = bars × 0.986923. This works because 1 bar equals exactly 0.986923 atm. To convert a value, multiply the number of bars by this factor. For example, 155 bars: 155 × 0.986923 = 152.986 atm, which is approximately 152.986 atm. This ensures accuracy for pressure measurements.
Conversion Example
- Convert 100 bars to atm:
- Multiply 100 by 0.986923
- 100 × 0.986923 = 98.6923 atm
- Result: 98.6923 atm
- Convert 200 bars to atm:
- 200 × 0.986923 = 197.3846 atm
- Result: 197.3846 atm
- Convert 50 bars to atm:
- 50 × 0.986923 = 49.34615 atm
- Result: 49.3462 atm
- Convert 10 bars to atm:
- 10 × 0.986923 = 9.86923 atm
- Result: 9.8692 atm

Conversion Definitions
Bars: A metric unit measuring pressure, where 1 bar equals 100,000 pascals, used in meteorology, engineering, and industrial processes to quantify pressure exerted by gases or liquids.
atm: Standard atmosphere, a pressure unit defined as 101,325 pascals, used worldwide to describe atmospheric pressure and pressure in various scientific and industrial contexts.
Conversion FAQs
Why is the conversion factor from bars to atm 0.986923?
This factor is based on the exact relation that 1 bar equals 0.986923 atm, derived from the definition of the bar as a metric unit of pressure and the standard atmosphere based on average sea-level pressure. It ensures precise conversions for scientific accuracy.
Can I use rounded figures for quick calculations?
Yes, for rough estimates, you can approximate 1 bar as 1 atm, but for exact measurements, always use 0.986923 as the conversion factor. Rounding can lead to slight inaccuracies that matter in sensitive applications.
Is the conversion valid for high-pressure systems?
The conversion applies universally, whether low or high pressure, because it is based on fixed definitions. However, in extreme conditions, always consider equipment limits and measurement accuracy beyond unit conversions.
How does temperature affect pressure conversions?
The conversion between bars and atm assumes standard temperature conditions. Variations in temperature can affect pressure readings, so conversions are most accurate when temperature is controlled or accounted for separately.
