How it's calculated
V = L × W × H
L = length, W = width, H = height (all converted to feet), V = volume in cubic feet. Other units derive from ft³ (× 1728 for in³, × 28.3168 for litres, × 7.48052 for US gallons).
Common questions
Can I mix units across dimensions?
Yes. Each dimension has its own toggle, so you can enter length in feet and depth in inches and it converts before multiplying.
How do I get cubic yards from this?
The result panel shows cubic yards directly. One cubic yard equals 27 cubic feet.
