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. 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.
To convert between Square Millimeter (mm²) and Are (a), use the following formulas:
1 Square Millimeter (mm²) = 1e-8 Are (a)
1 Are (a) = 100000000 Square Millimeter (mm²)
10 mm² = 10 * 1e-8 a = 1e-7 a
50 mm² = 50 * 1e-8 a = 5e-7 a
100 mm² = 100 * 1e-8 a = 0.000001 a
500 mm² = 500 * 1e-8 a = 0.000005 a
1000 mm² = 1000 * 1e-8 a = 0.00001 a
| Square Millimeter (mm²) | Are (a) |
|---|---|
| 1 mm² | 1e-8 a |
| 10 mm² | 1e-7 a |
| 100 mm² | 0.000001 a |
| 500 mm² | 0.000005 a |
| 1000 mm² | 0.00001 a |
