About both units

From

Square Millimeter

mm²

The square millimetre equals 1/1,000,000 of a square metre. Used in precision engineering, electronics (transistor size, chip area) and microscopy. The cross-section of an electrical cable is often specified in mm².

Real-world: Typical household wiring is 2.5 mm² copper. A grain of rice covers about 10 mm². A pin head is under 1 mm².

Dunam

dunam

The metric dunam equals 1000 square metres exactly. It is the standard land unit in Israel, Palestine, Turkey and parts of the former Ottoman Empire. Other regional "dunams" have existed historically, but the metric dunam (1000 m²) is the modern standard.

Real-world: An Israeli small farm might be 50 dunams (5 ha). Agricultural yields sometimes quoted per dunam.

Tips & common mistakes

Quick tips

1 mm² = 0.01 cm² = 10⁻⁶ m².
Electrical cables: 1 mm² up to 10 A; 2.5 mm² up to 16 A (EU standards).
Always convert to m² for large structures; mm² for precision parts.

Avoid these

Using mm² instead of cm² for medium-sized surfaces — clutters figures.
Confusing mm² with mm — different dimensions.
Assuming a cable rated at 1.5 mm² is 1.5 mm wide — it is the conductive cross-section.
