FAQ
How does the gravel & aggregate calculator work?
Crushed stone weighs about 1.4 tons per cubic yard. Driveways want at least 4 inches of base plus 2 inches of top course. The underlying maths is: Cubic yards = length × width × depth ÷ 27; tons = yards × density.
What do I need to enter?
5 values: length, width, depth, tons per cubic yard, and price per ton delivered. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the tons of gravel result mean?
It is returned as a decimal number and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
