Your inputs

Adjust the values to explore a different result.

Enter atoms per cell.
g/mol
Enter atomic molar mass in g/mol.
nm
Enter cell edge in nm.

Formula

density=atoms × molar mass /(N_A × edge³); nm³ converted to cm³.
  • Use the units shown beside each field.
  • Results update automatically whenever you change an input.
  • Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
  • Monatomic cubic unit cell, fully occupied. Defects, mixed species and thermal expansion are excluded.

Example Calculation

Example inputs
  • Atoms per cell: 4
  • Atomic molar mass: 63.546 g/mol
  • Cell edge: 0.3615 nm

4 atoms, molar mass 63.546 g/mol and edge 0.3615 nm give about 8.935 g/cm³.

Frequently asked questions

How do I use this calculator?

Enter atoms per cell, atomic molar mass, cell edge. The result updates automatically. Use Reset to restore the example values.

What method does it use?

density=atoms × molar mass /(N_A × edge³); nm³ converted to cm³.. Monatomic cubic unit cell, fully occupied. Defects, mixed species and thermal expansion are excluded.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
