What is ATM conversion? Atmospheric pressure converter

ATM, or atmosphere, is a unit of pressure that reflects the force exerted by the Earth's atmosphere at sea level. One ATM is equivalent to the pressure exerted by a 760 mm column of mercury at 0°C. It translates to about 101,325 Pascals or 14.696 PSI.

This unit is vital in fields like meteorology and aviation, where accurate pressure measurements are crucial. While ATM is a standard unit, pressure can also be measured in other units like Pascals or PSI, depending on the context and geographic location. Understanding ATM is essential for various scientific and practical applications, particularly where accurate atmospheric pressure readings are required.

How does ATM conversion work?

Now is the perfect time to explore key atmospheric unit conversion formulas for converting ATM to other units. These formulas are essential for understanding ATM atmospheric pressure conversions and can be helpful even without a specialized tool.

  • ATM to Bar

    To convert a value from ATM to bar, multiply the pressure in ATM by 1.01325. Here’s the formula:

    bar=ATM×1.01325\text{bar} = \text{ATM} \times 1.01325

    Conversely, to convert bar to ATM, divide bar by 1.01325.

  • ATM to Pascal

    For converting ATM to Pascal (Pa), multiply the pressure in ATM by 101,325. The formula is as follows:

    Pascal=ATM×101,325\text{Pascal} = \text{ATM} \times 101,325

    To reverse the conversion and get ATM from Pascal, divide Pa by 101,325.

  • ATM to psi

    When converting from ATM to psi, multiply ATM by 14.696. The formula is:

    psi=ATM×14.696\text{psi} = \text{ATM} \times 14.696

    And to convert psi back to ATM, divide psi by 14.696.


What is the ATM if the pressure is 200,000 Pa?

The atmospheric pressure (ATM) equivalent to 200,000 Pascals (Pa) is approximately 1.974 ATM. You may perform the atmospheric pressure conversion using this formula:

ATM = Pascal / 101,325.

How do I convert PSI to ATM?

You can convert PSI into ATM in three steps:

  1. Determine the amount of PSI to convert.
  2. Calculate the conversion factor, which is 14.696.
  3. Apply the ATM atmospheric unit conversion: ATM = PSI / 14.696.

Is the conversion from ATM to other units linear?

Yes, the conversion of ATM to other units follows a linear scale, where the values are multiplied by a constant conversion factor.

Does elevation affect ATM conversion?

Yes, atmospheric pressure decreases with elevation, impacting the accuracy of ATM values at higher altitudes, which is important for applications like aviation.
