This Ideal Gas Law Calculator calculates either the mass, volume, pressure or temperature of a gas sample if the gas type and the other variables are provided. Below the form you can discover more on this topic.
How does this ideal gas law calculator work?
Initially affirmed by Émile Clapeyron in 1834 (as a combination of other two existing gas laws of Boyle, respectively Charles), the common form of the ideal gas law is P*V = N*R*T, while its molar expression is P*V = (m/M)*R*T. It is being used to approximate the behavior of various gases under specific conditions.
Where:
P = gas pressure
V = gas volume
T = gas temperature
R = the ideal gas constant equal to 8314.4621
m = mass
M = molar mass (please note that m/M represents the number of moles - N).
For each gas type from the drop down list, this ideal gas law calculator uses the molar masses from the periodic table of Mendeleev and requires three out of the 4 fields available (plus the gas name).
Depending on the given variables the following measurement units can be used at the data input within the form:
Pressure is by default set up to Pa but can be expressed using one of these units:
From: |
To: Pa |
KPa |
1000 |
Bar |
100000 |
atm |
101325.01 |
mmHg |
895 |
mbar |

Volume is by default in m^{3}
From: |
To: m^{3} |
l |

ml |
0.000001 |
ft^{3} |
0.02831685 |
in^{3} |
0.00001638706 |
The temperature is by default in Kelvin but there are other two options: Celsius or Fahrenheit. lawyerfree.ru will automatically convert it to Kelvin by using these conversion rules:
From °C to K = t°C + 273.15
From °F to K = (t°F + 459.67) * 5/9
Mass is in kg, while there are other 3 units available:
