Type one volume. The other unit fills in. Bag counts use typical published yields so you can see the scale. This is unit math, not a concrete order.

Assumptions

One cubic yard is exactly 27 cubic feet. The converter divides or multiplies by 27. It does not add waste. Bag counts round up at 0.60 ft³ per 80 lb bag and 0.45 ft³ per 60 lb bag. Those yields are common published starting points. The bag in the aisle can list a different number.
