面積は、2次元の表面または形状の程度の尺度です。通常、平方メートル（m²）などの正方形ユニットで測定されます。
1 ac = 10 ground
1 ground = 0.1 ac
例:
15 エーカーを地面に変換します。
15 ac = 150 ground
| エーカー | 地面 |
|---|---|
| 0.01 ac | 0.1 ground |
| 0.1 ac | 1 ground |
| 1 ac | 10 ground |
| 2 ac | 20 ground |
| 3 ac | 30 ground |
| 5 ac | 50 ground |
| 10 ac | 100 ground |
| 20 ac | 200 ground |
| 30 ac | 300 ground |
| 40 ac | 400 ground |
| 50 ac | 500 ground |
| 60 ac | 600 ground |
| 70 ac | 700 ground |
| 80 ac | 800 ground |
| 90 ac | 900 ground |
| 100 ac | 1,000 ground |
| 250 ac | 2,500 ground |
| 500 ac | 5,000 ground |
| 750 ac | 7,500 ground |
| 1000 ac | 10,000 ground |
| 10000 ac | 100,000 ground |
| 100000 ac | 1,000,000 ground |
