About the Atmospheres Pressure Converter
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
1 atm = 101,325 Pa (exact, by definition)
PSI = atm x 14.696
bar = atm x 1.01325
mmHg = atm x 760
inHg = atm x 29.921
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: 1 atm = 101,325 Pa (exact, by definition) PSI = atm x 14.696 bar = atm x 1.01325 mmHg = atm x 760 inHg = atm x 29.921 Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Sea Level Standard Atmosphere
Inputs
With Atmospheres = 1 as the stated inputs, the result is PSI = 14.696 PSI, Bar = 1.01325 bar and kPa = 101.325 kPa. Each value corresponds to the declared output fields.
Example 2: Denver, CO Altitude: 0.832 atm
Inputs
With Atmospheres = 0.832 as the stated inputs, the result is PSI = 12.227 PSI, Bar = 0.84302 bar and kPa = 84.302 kPa. Each value corresponds to the declared output fields.
Example 3: SCUBA at 66 ft depth: 3 atm
Inputs
With Atmospheres = 3 as the stated inputs, the result is PSI = 44.088 PSI, Bar = 3.03975 bar and kPa = 303.975 kPa. Each value corresponds to the declared output fields.
Example 4: Commercial Aircraft Cabin Pressure: 0.77 atm
Inputs
With Atmospheres = 0.77 as the stated inputs, the result is PSI = 11.316 PSI, Bar = 0.7802 bar and kPa = 78.02 kPa. Each value corresponds to the declared output fields.
Common Use Cases
