The are (100 m²) is primarily used in European land measurement. A small urban garden might be 2-5 ares, while a modest house plot could be 10 ares. Though less common today, it still appears in some property documents and agricultural contexts. The square millimeter (mm²) is used for precision measurements in engineering and manufacturing. It's ideal for measuring tiny surfaces like electronic components (a microSD card is about 150 mm²) or paper thickness (standard printer paper is ~62,370 mm² per sheet). This unit is essential in microelectronics and quality control.
To convert between Are (a) and Square Millimeter (mm²), use the following formulas:
1 Are (a) = 100000000 Square Millimeter (mm²)
1 Square Millimeter (mm²) = 1e-8 Are (a)
1 a = 1 * 100000000 mm² = 100000000 mm²
5 a = 5 * 100000000 mm² = 500000000 mm²
10 a = 10 * 100000000 mm² = 1000000000 mm²
50 a = 50 * 100000000 mm² = 5000000000 mm²
| Are (a) | Square Millimeter (mm²) |
|---|---|
| 1 a | 100000000 mm² |
| 5 a | 500000000 mm² |
| 10 a | 1000000000 mm² |
| 50 a | 5000000000 mm² |
| 100 a | 10000000000 mm² |
