What to enter
| Input | Meaning and units |
|---|---|
| Amount (mol) | Enter amount in mol; use the same basis as the other measurements. |
| Absolute temperature (K) | Enter absolute temperature in K; use the same basis as the other measurements. |
| Volume (m³) | Net volume in cubic metres. Convert cubic units before entering the value; outside dimensions of hollow objects are not net material volume. |
Understanding your result
Read Absolute pressure (Pa) in the units and model stated on this page. The formula pressure=n*8.31446261815324*T/V defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
