The conversion of 155 bars results in approximately 152.56 atm.
This is because 1 bar equals exactly 0.98692 atm, so multiplying 155 bars by this factor gives the atm value. This conversion uses the precise ratio between the two units, ensuring accuracy in pressure measurements.
Understanding the conversion from bars to atm
To convert bars to atm, you take the number of bars and multiply it with 0.98692. This works because both units measure pressure, but atm is based on the Earth’s atmospheric pressure at sea level, while bar is a metric unit. The ratio allows conversion between these units directly.

Conversion Formula
The formula to convert bars to atm is pressure_in_atm = pressure_in_bars * 0.98692. It works because 1 bar equals exactly 0.98692 atm, so multiplying the number of bars by this factor gives the pressure in atm. For example, 200 bars * 0.98692 = 197.384 atm.
Conversion Example
- Convert 100 bars to atm:
- Step 1: Take 100 (bars).
- Step 2: Multiply by 0.98692.
- Step 3: 100 * 0.98692 = 98.692 atm.
- Convert 50 bars:
- Step 1: 50 bars.
- Step 2: 50 * 0.98692.
- Step 3: 49.346 atm.
- Convert 200 bars:
- Step 1: 200 bars.
- Step 2: 200 * 0.98692.
- Step 3: 197.384 atm.
- Convert 155 bars (our main example):
- Step 1: 155 bars.
- Step 2: 155 * 0.98692.
- Step 3: 152.0566 atm.
- Rounded to 152.06 atm for simplicity.

Conversion Definitions
Bars
Bars are units measuring pressure, especially used in meteorology, engineering, and industrial contexts, defined as 100,000 pascals or newtons per square meter, representing pressure exerted by a force over an area, often used in compressed gases or tire pressures.
atm
Atmospheres (atm) measure pressure based on Earth’s average sea level atmospheric pressure, roughly equal to 101,325 pascals, used mainly in scientific and engineering applications to express pressure relative to this standard.
Conversion FAQs
What is the difference between bars and atm in pressure measurement?
Bars and atm both measure pressure but differ in their reference standards; bars are metric units, with 1 bar = 100,000 pascals, whereas atmospheres are based on Earth’s sea level pressure, with 1 atm = 101,325 pascals. The conversion uses the ratio between these units.
Why does converting 155 bars to atm give about 152.56 atm?
This is because multiplying 155 by 0.98692, the conversion factor, results in approximately 152.56, reflecting the pressure in atm equivalent to 155 bars based on precise unit ratios used in scientific measurements.
Can I use a simple multiplication to convert bars to atm?
Yes, because 1 bar equals exactly 0.98692 atm, multiplying the number of bars by this factor gives the pressure in atm directly. This method is fast and accurate for pressure conversions.
What tools are available for converting bars to atm?
