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 ground = 484.001 yd²
1 yd² = 0.002 ground
例子:
将15 地面转换为方院：
15 ground = 7,260.01 yd²
| 地面 | 方院 |
|---|---|
| 0.01 ground | 4.84 yd² |
| 0.1 ground | 48.4 yd² |
| 1 ground | 484.001 yd² |
| 2 ground | 968.001 yd² |
| 3 ground | 1,452.002 yd² |
| 5 ground | 2,420.003 yd² |
| 10 ground | 4,840.006 yd² |
| 20 ground | 9,680.013 yd² |
| 30 ground | 14,520.019 yd² |
| 40 ground | 19,360.025 yd² |
