mm² = m² × 1000000A square millimeter is tiny — the size of a pinhead. A square meter is a full meter on each side, or 1 million mm². Microelectronics manufacturers, precision engineers, and materials scientists work across this 6-order-of-magnitude range when sizing components, dies, or test specimens.
