How It Works

The calculator uses the formula: Volume × Unit Weight = Total Weight

Calculation Steps:

  1. Calculate area: Length × Width (or use provided area)
  2. Calculate volume: Area × Depth (with proper unit conversion)
  3. Calculate weight: Volume × Material Unit Weight
  4. Convert to tons: Weight ÷ 2000 (for US tons) or Weight ÷ 1000 (for metric tonnes)

Coverage Reference (Approximate)

Material 1 Ton Covers (at 2 inches) 1 Ton Covers (at 4 inches)
Washed Stone ~120 ft² ~60 ft²
Screenings ~165 ft² ~82 ft²
Sand ~160 ft² ~80 ft²

Frequently Asked Questions

How many tons does 1 cubic yard of gravel weigh? +

One cubic yard of gravel typically weighs between 2,400 to 2,900 pounds (1.2 to 1.45 tons). The exact weight depends on the type of gravel and its density.

How to calculate area if only one dimension is known? +

If you only know one dimension (like the length of a driveway), you’ll need to estimate the width. For example, a typical residential driveway is about 10-12 feet wide. Multiply length by estimated width to get area.

Why use unit weight in calculation? +

Unit weight (density) varies by material type. Gravel is denser than sand, which is denser than topsoil. Using the correct unit weight ensures accurate weight calculations for your specific material.

What’s the difference between US tons and metric tonnes? +

A US ton (short ton) is 2,000 pounds, while a metric tonne is 1,000 kilograms (approximately 2,204.6 pounds). Metric tonnes are about 10% heavier than US tons.

How accurate is this calculator? +

This calculator provides estimates based on standard material densities. Actual weights can vary based on moisture content, compaction, and specific material composition. For critical applications, consult with your material supplier.
