Why does soil weight vary?
Moisture, organic content and compaction can materially change bulk density.

Topsoil Calculator — Volume, Tonnes & Bags
Calculate topsoil volume from area and depth, then estimate cubic yards, cubic meters, mass from density and bag count.
Result
0.636 yd³
0.486 m³ · 4.9 kg at entered density
244 bag(s) at 2 L; allowance 3%.
Formula and worked example
Volume = area × depth; mass = volume × bulk density; bags = ceil(volume ÷ bag volume).
A 100 ft² bed at 6 in depth requires 50 ft³, approximately 1.852 yd³.
Assumptions
- Bulk density is user-entered because soil composition and moisture change mass.
- Compaction is not hidden; add an allowance if your project requires it.

Frequently asked questions
Can I calculate raised beds?
Yes, use the bed footprint as area and desired soil depth as depth.
