How to use this calculator

Measure, verify, and order

Field and unit guide

What each input means

Starting measurement

Choose whether you already know cubic yards or need volume from dimensions.

Use known volume from plans or dimensions from the jobsite.

Volume

Known loose or compacted cubic yards to convert.

Unit: cu yd. Enter the supplier or plan volume in cubic yards.

Length

Project length when calculating volume from dimensions.

Unit: ft or m. Measure the long side in feet.

Width

Project width when calculating volume from dimensions.

Unit: ft or m. Measure the short side in feet.

Depth

Material depth used with length and width.

Unit: in or cm. Measure finished thickness in inches.

Material density

Bulk density used to convert cubic feet into weight.

Unit: lb/ft3 or kg/m3. Use the supplier value in pounds per cubic foot when available.

Price per ton

Optional supplier price used to estimate material cost before delivery fees and taxes.

Unit: USD per US ton. Enter the quoted material price per US short ton. Leave 0 if you only need quantity.
Worked example

Check the calculation

Example: 1 cubic yard equals 27 cubic feet. At 100 lb/ft3, it weighs 2,700 lb, or 1.35 short tons.

A 10 × 10 ft area at 3 inches deep holds 0.93 compacted cubic yards. At 100 lb/ft³, that is about 1.25 US tons before allowances.

Total loose order 0.93 cu yd Total weight 1.25 US tons

Weight = cubic feet x bulk density. Cubic yards x 27 = cubic feet.

Before ordering

Assumptions to check

  • Choose the closest material density.
  • Wet or tightly graded stone can weigh more.
  • Supplier scale tickets determine the final delivered weight.
  • Weight is not exact without supplier density.
  • Moisture can materially change tonnage.
  • Does not replace truck scale measurements.

Frequently Asked Questions

What does this gravel weight and tonnage calculator calculate?

It uses project-specific inputs and the formula shown below. Weight = cubic feet x bulk density. Cubic yards x 27 = cubic feet.

Are the presets exact specifications?

No. Presets are editable planning starting points. Confirm depths, materials, and densities with the supplier, manufacturer, or project designer.

Why can delivered weight differ?

Bulk density varies by supplier and moisture level. Moisture, gradation, compaction, and scale accuracy can change the delivered weight.
