Area conversion
3 units, with m² as the base. Every value in the factor table is the number you multiply by, so reading across a row converts out of that unit and reading down a column converts into it.
Factor table
| from \ to | mm² | cm² | m² |
|---|---|---|---|
| mm² | 1 | 0.01 | 1 × 10⁻⁶ |
| cm² | 100 | 1 | 1 × 10⁻⁴ |
| m² | 1 × 10⁶ | 10,000 | 1 |
Prefixes such as milli, micro and kilo follow the SI prefixes table.

Worked example
- 1 cm² in m²
- = 1 × (1 × 10⁻⁴)
- = 1 × 10⁻⁴ m²

The table gives the factor; the unit converter does the arithmetic, remembers the units you picked, and turns any conversion into a link you can share.
