Reference

How area conversion works

Area measures a two-dimensional surface. Linear conversion factors must be squared, so one meter to feet is not the same factor as one square meter to square feet.

Values are converted to square meter first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: Values derived from exact metric and international length definitions.
