About Hectares and Square inches
Hectares (ha): Ten thousand square meters, or 100 m × 100 m; from the Greek hekaton meaning hundred (referring to the hundred-fold of an are, an obscure unit). Common uses: Land area in metric countries — agriculture, forestry, real estate (especially rural), and conservation.
Square inches (in²): One inch squared, or 6.4516 cm² exactly (since the inch is defined as 2.54 cm exactly). Common uses: Small flat areas in US contexts — phone screens, computer chip die sizes, postal stamps, and small fabricated parts.
