Understanding gas behavior is essential in physics, chemistry, and engineering. Our PV=nRT Calculator helps students and professionals quickly solve gas law equations using the Ideal Gas Law formula.
This tool belongs to our website and is built specifically to calculate one missing variable in the PV=nRT equation.
What Is PV=nRT?
The Ideal Gas Law formula is:
PV = nRT
Where:
P = Pressure
V = Volume
n = Number of moles
R = Gas constant
T = Temperature (Kelvin)
What Does This Calculator Do?
It calculates one unknown value when the other three are provided.
Required Inputs
You must provide:
- Any three of the four variables (P, V, n, T)
The gas constant R is standard (0.0821 L·atm/mol·K or 8.314 J/mol·K depending on units).
Outputs
The calculator provides:
- The missing variable value
How to Use the PV=nRT Calculator

Practical Example
Given:
P = 2 atm
V = 10 L
n = 1 mol
R = 0.0821
Solve for T:
T = PV / nR
T = (2 × 10) / (1 × 0.0821)
T ≈ 243.6 K
