The tonnage calculator assists in the tonnage of aggregates required for specific areas and depths typically in the shipping and logistics industry. This online tool estimates the space or weight of a shipment, essential for planning and pricing.

What is Tonnage?

It is the capacity or size of aircraft, ship, or other vehicles measured in weight or volume is known as tonnage. In the context of shipping, it is also known as the total weight of a ship’s cargo and fuel.

How Gravel Tonnage Calculator Work?

There is a simple way to use the online gravel calculator tons. Just follow the below steps and insert the values.

Required Values:

  • Choose the type of material
  • Enter the unit weight in kg/m^3
  • Enter length, width, and depth
  • Provide data about the material cost
  • Tap on calculate

Results Summary:

  • Tonnage
  • Area
  • Volume
  • Weight Needed
  • Total Cost

Tonnage Formula:

\(W = V \times \gamma \times 0.001 , \text{tons} / \text{kg}\)

  • W = Tonnage of aggregates (in tons)
  • V = Aggregates’ volume (in cubic meters)
  • γ = Aggregates’ unit weight (in kilograms per cubic meter)

How Do You Calculate Tonnage?

To calculate the tonnage, typically you need to convert weight of products from pounds to tons. In the below section, there is an example that will clear your understanding of their calculation process.

Practical Example:

Let’s calculate the tonnage of a shipment weighing 4,500 pounds.


To determine the tonnage of the shipment, we’ll use the formula:

\(\text{Tonnage} = \frac{weight (in pounds)}{2000}\)

\(\text{Tonnage} = \frac{4500}{2000}\)

\(\text{Tonnage} = 2.25, \text{tons}\)

Additional Questions:

What Area Will 1 Ton of Gravel Cover?

100 square feet

The covered area by 1 ton depends on the depth of the gravel layer. As a roughly estimated 1 ton of gravel covers 100 square feet at a depth of 2 inches.

How Much HVAC Do I Need For 2,000 Square Feet?

Around 3 tons

Typically a 2,000-square-foot home will require about 3 tons of AC units.

How Many BTU Equals a Ton?

12,000 BTU

1 ton of cooling capacity is equivalent to 12,000 British Thermal Units (BTUs) per hour.
