Pea gravel quantity begins with area × depth. Convert cubic yards to tons only with the supplier's density for the selected material, because rounded aggregate source and moisture affect bulk weight.
Pea-gravel volume = area × depth; cubic yards = cubic feet ÷ 27. Convert volume to tons with the selected supplier's bulk-density basis rather than borrowing a crushed-stone conversion.

Convert depth to feet, multiply by square feet, then divide cubic feet by 27 for cubic yards.
Use actual finished coverage boundaries.
Bulk tons = volume × supplier tons-per-yard basis.
Do not reuse crushed-stone density automatically for pea gravel.
Apply a transparent allowance only after geometric quantity is known.
Bagged and bulk material should be compared on equivalent volume or mass bases.
Rounded pea gravel behaves differently from angular compactable base aggregate.
Confirm that the selected material is appropriate for the intended assembly.
Estimate river rock or decorative landscape stone from bed area, target depth, rock size, and supplier-specific bulk density or bag coverage.
Read guide →Gravel & StoneEstimate decomposed granite from finished area and compacted depth, then convert to supplier volume or tons with compaction kept explicit.
Read guide →Gravel & StoneCompare crushed-stone and limestone base quantities using compacted volume, supplier density, gradation, and project specification rather than material name alone.

| Step | Calculation | Result |
|---|---|---|
| Depth | 3÷12 | 0.25 ft |
| Volume | 300×0.25 | 75 cu ft |
| Cubic yards | 75÷27 | 2.78 yd³ |
| Tons | 2.78×supplier factor | Verify |
Current manufacturer data, supplier specifications, drawings, field measurements, applicable codes, permit requirements, and qualified professional guidance can take priority over a general-purpose planning estimate.
