This Boyle-Mariotte Law Calculator can estimate the pressure or the volume change of gas if you provide 3 out of the 4 variables in the Boyle-Mariotte’s equation where the temperature (t) is constant. You can get the formulas used below the form.

Instruction: Please input three fields from the four below!

Pressure 1 (p1):*
Volume 1 (V1):*
Pressure 2 (p2):*
Volume 2 (V2):*

## How does this Boyle-Mariotte Law Calculator work?

This tool can be used to compute any change in pressure or volume of gas by taking account of the Boyle-Mariotte’s Law which states that when mass and temperature are kept constant the volume of the gas will vary inversely with the pressure it is exposed to. This law can be written by the formulas detailed below that are used by the algorithm of this calculator:

Boyle-Mariotte Law formula: P1*V1= P2*V2

Each of the variables in the equation can be determined if the other 3 variables are given:

-  P1 and P2 equations:

P1 = P2*V2/V1

P2 = P1*V1/V2

-  V1 and V2 formulas:

V1 = P2*V2/P1

V2 = P1*V1/P2

Where:
P1 is the initial pressure;

V1 is the initial volume;

P2 is the pressure changed;

V2 is the volume changed;

Assumption: Temperature (t) and Mass (m) stay constant.

This calculator can support multiple units depending on the variable type as described in the following tables with conversion rates:

- For Volume the default unit in the SI is m3:

 From: To: m3 l 0.001 ml 0.000001 ft3 0.02831685 in3 0.00001638706

- For Pressure the default unit in the SI is  Pa:

 From: To: Pa KPa 1000 Bar 100000 atm 101325.01 mmHg 133.32238157895 mbar 100
