Chemistry & Thermodynamics: The 4 Combined Gas Laws in PV = nRT
The Ideal Gas Law mathematically synthesizes the four classical empirical gas laws into a single equation of state:
- Boyle's Law: \ (Pressure and volume are inversely proportional at constant T).
- Charles's Law: V T (Volume is directly proportional to absolute Kelvin temperature).
- Gay-Lussac's Law: P T (Pressure is directly proportional to temperature).
- Avogadro's Law: V n.
How to Use This Calculator
Enter your Select Variable to Solve — choose from Pressure (P) -- Solve P = nRT / V, Volume (V) -- Solve V = nRT / P, Moles (n) -- Solve n = PV / RT, Pressure (P in Atmospheres atm) (e.g. 2.5), Volume (V in Liters L) (e.g. 10.0), Amount of Gas (n in Moles) (e.g. 1.0), Temperature (T in Celsius °C) (e.g. 25.0 (Standard room temperature)), and Molar Mass of Gas (g / mol) [e.g. N2 = 28.01, O2 = 32.0, CO2 = 44.01] (e.g. 28.97 (Air average)). Verify your units match the formula standard (SI vs imperial) before entering values.
The Formula
Ideal Gas Law & kinetic molecular thermodynamics equations: × V = n × R × T: P = (nRT) / (V), Volume: V = (nRT) / (P): n = (PV) / (RT), Temperature: T = (PV) / (nR) Gas Constant: R = 0.082057 (L·atm) / (mol·K) = 8.31446 (J) / (mol·K) Density (ρ) = (P × M) / (R × T) (M = Molar Mass in g/mol) Translational Kinetic Energy = (3) / (2) R T

Understanding Your Result
Scientific calculations require careful attention to significant figures and units. Your result is only as precise as your least precise input — expressing the result with more significant figures than the inputs implies false precision. For laboratory or regulatory work, verify which measurement standard applies (SI, ASTM, ISO) and whether temperature, pressure, or concentration conditions affect the formula. Cross-reference results against published reference values for your specific material or compound.
