1 atm equals approximately 0.1013 mpa.
Table of Contents
Converting atmospheres to mpa involves multiplying the atm value by 0.1013, because 1 atm is exactly 0.1013 mpa. This conversion is based on the established relationship between these pressure units, where atm measures pressure in Earth’s atmosphere, and mpa measures in megapascal.

Conversion Formula
The conversion formula from atm to mpa is: mpa = atm × 0.1013. It works because 1 atm is defined as exactly 101,325 pascals, and 1 mpa equals 1,000,000 pascals. Dividing 101,325 by 1,000,000 results in 0.1013, which is used for conversion, ensuring accuracy.
For example, to convert 2 atm to mpa: 2 × 0.1013 = 0.2026 mpa. This step-by-step multiplication applies the fixed conversion factor consistently across all values, making it straightforward to switch between units.
Conversion Example
- Convert 1 atm:
- Multiply 1 by 0.1013
- Result: 0.1013 mpa
- Convert 5 atm:
- Multiply 5 by 0.1013
- Result: 0.5065 mpa
- Convert 0.5 atm:
- Multiply 0.5 by 0.1013
- Result: 0.0507 mpa
- Convert 10 atm:
- Multiply 10 by 0.1013
- Result: 1.0130 mpa
- Convert 0.2 atm:
- Multiply 0.2 by 0.1013
- Result: 0.0203 mpa

Conversion Definitions
atm
Atmosphere (atm) is a pressure unit based on Earth’s average sea level pressure, defined as 101,325 pascals. It is widely used in meteorology, scuba diving, and engineering to measure atmospheric and gas pressures relative to standard sea level conditions.
mpa
Megapascal (mpa) is a pressure unit equal to one million pascals. It is used in engineering, material science, and high-pressure physics to quantify stress, pressure, and force per unit area with precision, especially in contexts requiring large pressure measurements.
Conversion FAQs
Why is the conversion factor from atm to mpa 0.1013?
This factor stems from the fact that 1 atm equals 101,325 pascals, and since 1 mpa is 1,000,000 pascals, dividing 101,325 by 1,000,000 gives approximately 0.1013. This fixed ratio ensures consistent conversions across units.
Can I convert other units to mpa using the same factor?
Not directly. Different units like psi or bar have their own conversion factors to pascals, and then to mpa. To convert such units to mpa, first convert them to pascals using their specific factors, then divide by 1,000,000.
What happens if I input a negative atm value in the converter?
Negative pressure values are physically unusual but mathematically possible. The converter will multiply the negative value by 0.1013, resulting in a negative mpa, which can be relevant in specialized scientific contexts involving vacuum or tension.
