How to calculate
Normalize volume to cubic meters and amount of substance to moles.
Molar volume in m³/mol = value × volume factor / amount factor
Worked example
22.4 L/mol equals 22.4 m³/kmol and 0.0224 m³/mol.
Assumptions and input details
The entered volume retains its stated pressure, temperature and phase. No standard gas conditions, ideal-gas assumption or substance identity is supplied. A pound-mole is 453.59237 mol. Molar volume differs from ordinary volume and volume per unit mass; converting those needs amount or molar mass.

Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
