面积是二维表面或形状范围的度量。它通常以平方米（例如平方米（平方米））为单位进行测量。
1 a = 100,000,000 mm²
1 mm² = 1.0000e-8 a
例子:
将15 是转换为方形毫米：
15 a = 1,500,000,000 mm²
| 是 | 方形毫米 |
|---|---|
| 0.01 a | 1,000,000 mm² |
| 0.1 a | 10,000,000 mm² |
| 1 a | 100,000,000 mm² |
| 2 a | 200,000,000 mm² |
| 3 a | 300,000,000 mm² |
| 5 a | 500,000,000 mm² |
| 10 a | 1,000,000,000 mm² |
| 20 a | 2,000,000,000 mm² |
| 30 a | 3,000,000,000 mm² |
| 40 a | 4,000,000,000 mm² |
| 50 a | 5,000,000,000 mm² |
| 60 a | 6,000,000,000 mm² |
| 70 a | 7,000,000,000 mm² |
| 80 a | 8,000,000,000 mm² |
| 90 a | 9,000,000,000 mm² |
| 100 a | 10,000,000,000 mm² |
| 250 a | 25,000,000,000 mm² |
| 500 a | 50,000,000,000 mm² |
| 750 a | 75,000,000,000 mm² |
| 1000 a | 100,000,000,000 mm² |
| 10000 a | 1,000,000,000,000 mm² |
| 100000 a | 10,000,000,000,000 mm² |
