Converting Stone Volume to Tons
The stone tonnage calculator is a vital tool for budgeting and ordering materials for your project. While you might plan your project's area and depth to find the required volume (in cubic yards), suppliers price and sell materials by weight (in tons). This calculator seamlessly converts your volume into the tonnage you need to order.
The conversion relies on the density of the specific material you choose. By selecting your stone type, the tool applies the correct density factor to provide an accurate weight estimate. This prevents confusion at the supply yard and ensures you purchase the correct amount of material for your job.
Frequently Asked Questions
Why is stone sold by the ton?
Weight is a more consistent and reliable measure for bulk materials than volume. A ton is always 2,000 pounds, whereas the volume of a pile of stone can vary with moisture and stacking. Selling by weight is the industry standard for fairness and accuracy.
How many tons are in a cubic yard of gravel?
A cubic yard of typical gravel weighs approximately 1.4 tons (2,800 pounds). However, this can vary slightly based on the specific type and size of the gravel. Our calculator uses standard densities for its estimates.
How many cubic feet are in a ton of stone?
There are roughly 20-22 cubic feet in a ton of crushed stone. This number changes based on the stone's density. Denser materials will have fewer cubic feet per ton.
What is the difference between a ton and a tonne?
A "ton" in the US refers to a short ton, which is 2,000 pounds. A "tonne" (or metric ton) is 1,000 kilograms, or about 2,204.6 pounds. Landscaping materials in the US are sold by the short ton.
How do I calculate the weight of a stone slab?
To calculate a slab's weight, you first find its volume in cubic feet (Length x Width x Thickness). Then, you multiply that volume by the density of the stone type (e.g., granite is about 170 lbs per cubic foot). Our slab weight calculator automates this.
Can I trust the weight estimate from this calculator?
Yes, our calculator uses industry-standard density figures to provide a very reliable estimate for budgeting and ordering. It's an excellent tool for planning your purchase.
