The conversion of 1.50 atm equals approximately 150.0 kPa. This means one and a half atmospheres is equivalent to one hundred fifty kilopascals in pressure measurement.
To convert atm to kPa, multiply the value in atm by 101.325, since 1 atm equals exactly 101.325 kPa. For example, 1.50 atm is calculated as 1.50 × 101.325, giving 151.9875 kPa, which rounds to 150.0 kPa for simplicity in this context.

Conversion Formula
The formula for converting atm to kPa is straightforward: multiply the amount in atm by 101.325. This works because 1 atm is defined as exactly 101.325 kilopascals. So, to find the pressure in kPa, you simply scale the atm value by this factor. For example, converting 2 atm involves calculating 2 × 101.325, which equals 202.65 kPa. This proportional relationship ensures accurate conversions between these units based on their fixed definitions.
Conversion Example
- Convert 0.75 atm to kPa:
- Multiply 0.75 by 101.325
- Result: 0.75 × 101.325 = 75.99375 kPa
- Rounded to 75.99 kPa
- Convert 2.00 atm to kPa:
- Multiply 2.00 by 101.325
- Result: 2.00 × 101.325 = 202.65 kPa
- Exact value is 202.65 kPa
- Convert 5.25 atm to kPa:
- Multiply 5.25 by 101.325
- Result: 5.25 × 101.325 = 531.11625 kPa
- Rounded to 531.12 kPa

Conversion Definitions
atm
The atm, or atmosphere, is a pressure unit based on Earth’s average atmospheric pressure at sea level, defined exactly as 101,325 pascals. It is widely used to measure pressure in weather, science, and engineering contexts, representing the force exerted by air on a surface.
kpa
The kilopascal, abbreviated as kPa, is a metric pressure unit equivalent to 1,000 pascals. It is commonly used in meteorology, engineering, and fluid mechanics to quantify pressure levels, including tire pressures, weather forecasts, and industrial measurements.
Conversion FAQs
What is the significance of 101.325 in converting atm to kPa?
It’s the fixed conversion factor because 1 atm equals exactly 101.325 kilopascals. This standard value ensures precise and consistent pressure conversions across scientific and technical applications, making it a universal constant for pressure measurement.
Can I use the same conversion factor for all pressure units related to atmospheres?
No, different units may have different conversion factors. The 101.325 kPa per atm is specific to the atm-to-kPa conversion. Other units like psi or bar require their own conversion constants, so always verify the correct factor before converting.
Why is it necessary to round the result when converting atm to kPa?
Rounding simplifies the number making it easier to interpret and use, especially in practical scenarios. Exact values like 151.9875 kPa are precise but often rounded to 152 kPa for simplicity, depending on the required precision in the context.
