About Gravel Calculator

Calculates both volume (cubic yards) and weight (tons) of gravel, crushed rock, or aggregate required for landscape and driveway construction.

What is Gravel Calculator?

Calculates both volume (cubic yards) and weight (tons) of gravel, crushed rock, or aggregate required for landscape and driveway construction.

How to Use This Calculator

  1. Enter project length and width in feet.
  2. Enter desired gravel depth in inches.
  3. Select material density.
  4. Read tons and cubic yards needed.

The Mathematical Formula & Variables

Cubic Yards = [Length * Width * (Depth / 12)] / 27; Tons = Cubic Yards * Density (tons/yd³)

Step-by-Step Worked Example

Scenario: Driveway area 30 ft x 18 ft at 3 inches deep using standard crushed gravel (1.4 tons/yd³).

  1. Area = 30 * 18 = 540 sq ft.
  2. Volume = 540 * (3 / 12) = 135 cu ft = 5.00 cubic yards.
  3. Tons = 5.00 cu yds * 1.4 tons/yd³ = 7.00 tons.

Result: 7.00 Tons (5.00 Cubic Yards)

Frequently Asked Questions
