|---|---|---|---|---|
| 1 in | 0.46 yd³ | 12.5 ft³ | 13 | 0.23 |

For amending beds, spread 1–3 inches of compost and work it into the top 6 inches of soil. For lawn top-dressing, ¼–½ inch is plenty.
The math: 150 sq ft × depth in feet ÷ 27 = cubic yards. One cubic yard of compost covers 324 sq ft at 1" · 162 sq ft at 2" · 108 sq ft at 3".
Compost compresses — if it will sit in a pile for weeks before spreading, order about 10% extra.
