About the Pressure Calculator

Pressure is treated here as a quantitative relation between Force, Area and Pressure - to convert and Pressure, Pressure, Pressure and Pressure.

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:
P = F / A
P = Pressure (Pa)
F = Force (N)
A = Area (m^2)
PSI = Pa / 6,894.757
bar = Pa / 100,000
atm = Pa / 101,325
mmHg = Pa / 133.322

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:

P = F / A
P = Pressure (Pa)
F = Force (N)
A = Area (m^2)
PSI = Pa / 6,894.757
bar = Pa / 100,000
atm = Pa / 101,325
mmHg = Pa / 133.322

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: Car Tire Pressure

Inputs

force: 5560 area: 0.0128
Pressure: 434,375 Pa. Pressure: 63.0008 psi. Pressure: 4.34375 bar. Pressure: 4.28695 atm. Pressure: 3,258.09 mmHg

With Force = 5,560 and Area = 0.0128 as the stated inputs, the result is Pressure = 434,375 Pa, Pressure = 63.0008 psi and Pressure = 4.34375 bar. Each value corresponds to the declared output fields.

Example 2: Standard Atmosphere Conversion

Inputs

pressure_pa: 101325
Pressure: 101,325 Pa. Pressure: 14.6959 psi. Pressure: 1.01325 bar. Pressure: 1 atm. Pressure: 760 mmHg

With Pressure - to convert = 101,325 as the stated inputs, the result is Pressure = 101,325 Pa, Pressure = 14.6959 psi and Pressure = 1.01325 bar. Each value corresponds to the declared output fields.

Example 3: Hydraulic Press Force

Inputs

area: 0.002

With Area = 0.002 as the stated inputs, the result is the stated variables. Each value corresponds to the declared output fields.

Example 4: SCUBA Diver at Depth

Inputs

pressure_pa: 405300
Pressure: 405,300 Pa. Pressure: 58.7838 psi. Pressure: 4.053 bar. Pressure: 4 atm. Pressure: 3,040.01 mmHg

With Pressure - to convert = 405,300 as the stated inputs, the result is Pressure = 405,300 Pa, Pressure = 58.7838 psi and Pressure = 4.053 bar. Each value corresponds to the declared output fields.
