How many tons are in a cubic yard of pea gravel?

Multiply cubic yards by your supplier’s bulk density. The editable 1.35 US tons per cubic yard is a planning example, not a measured value for your gravel. Moisture and grading change the conversion. A US short ton is 2,000 lb; it is not a metric tonne.

How do I estimate pea gravel cost?

Enter your quoted price per cubic yard, plus any separate delivery charge and tax. The calculator uses the rounded cubic-yard purchase quantity. Convert a quote per ton before entering it; do not enter a per-ton price as a per-yard price.

Can I use the calculator for bags of pea gravel?

Convert the adjusted cubic yards to cubic feet by multiplying by 27, divide by the bag’s labelled cubic-foot volume, and round up. Bag weight alone requires a supplier density conversion.

Does the estimated tonnage use the rounded order volume?

The weight output uses volume with allowance before half-yard purchase rounding. If the supplier sells the rounded cubic-yard quantity, multiply that order quantity by the confirmed density for its delivery weight.

Pea Gravel Calculator

Estimate pea gravel volume and weight for a measured layer.

Enter your measurements below and the result updates as you type. Check the visible assumptions before ordering.

Formula and source notes

The formula is: measured quantity is volume = area × finished depth; weight = volume × density; allowance is adjusted quantity = measured quantity × (1 + allowance ÷ 100); order rounding is purchase quantity = adjusted quantity rounded up to a purchasable unit.

This calculation uses no default material density or yield; its product values and allowances come from the visible inputs and should be checked against the drawing, label or supplier.

Result

Plan to order 3.5 cubic yards of pea gravel.

Review the calculation methodology to see which figures are exact geometry, which depend on material assumptions, and which figures have recorded sources. The source registry records every cited figure and its review status.

How much pea gravel do I need?

Measure length and width, choose the finished layer depth, and enter the units beside each dimension. The calculator returns measured cubic yards, volume with allowance, an order quantity rounded to half-yard increments and estimated weight in US short tons.

At 12 ft × 10 ft and 3 inches deep, the measured volume is 1.11 yd³. With 10% allowance it is 1.22 yd³, which rounds to 1.5 yd³ to order. At an illustrative density of 1.35 US tons/yd³, the unrounded adjusted volume weighs about 1.65 US tons. If ordering the rounded 1.5 yd³, confirm its corresponding weight with the supplier.

1 inch	324 ft²	0.31 yd³
2 inches	162 ft²	0.62 yd³
3 inches	108 ft²	0.93 yd³
