Understanding your result
The answer estimates quantity, coverage or cost from the dimensions and allowances you entered. It does not size a structural member, assess capacity or determine installation adequacy.
Common mistakes
- Mixing centimetres with metres, or outside dimensions with the actual filled volume.
- Treating allowance, compaction, supplier yield and density as interchangeable adjustments.
Check your calculation
- Measure independently, subdivide irregular shapes, and compare supplier pack/yield information with the units used here.
