Ideal gas pressure

Estimate pressure with the ideal-gas model and keep its assumptions visible.

Start with the idea

This calculator is a scientific workspace. Read the quantities and units first; use the equation only after the physical meaning is clear.

P = nRT/V

Reference constant used by this model where applicable: 8.31446261815324. Keep SI units consistent before interpreting a numerical result.
