Ideal gas pressure
Calculate pressure from amount, absolute temperature, and volume using the ideal gas model.
Method and scope
P = nRT/V, using R = 8.314462618 J/(mol·K).
Use ideal gas pressure for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Gas amount — mol, mmol
- Absolute temperature — K, °C, °F
- Gas volume — m³, L, mL
SOURCE AND LIMITS
Assumptions: Gas behavior is ideal under the stated conditions. Temperature is absolute kelvin and volume is the gas volume.
Limitations: The ideal-gas approximation is less accurate at high pressure or near condensation.
