## Material Calculators

### Crushed Rock Calculator

The following formula gives you an estimate of the amount of material you will need to do a project using the following materials: 4″ – 0, 3″ – 0, 1 1/2″ – 0, 3/4″ – 0, 1/2″ – 0, 1/4″ – 0.

First, multiply Length x Width x Depth in feet, to get the total Cubic Footage. Next take the total Cubic Footage result and divide it by 27 to give you your total Cubic Yards quotient. Then take your total Cubic Yards and multiply it by 1.95 to find the total estimated tons needed for your project.

### Drain Rock Calculator

This calculator estimates with the following materials: 1 1/2″ x 3/4″ Round Rock, 3/4″ x 1/4″ Round Rock, 3/8″ Pea Rock, Sand, 1 1/2″ x 3/4″ Crushed Drain Rock, or 3/4″ x 1/4″ Crushed Drain Rock.

First, multiply Length x Width x Depth, in feet, to get the total Cubic Footage. Next take the total Cubic Footage result and divide it by 27 to get your total Cubic Yards. Then take your total Cubic Yards result and multiply it by 1.5 to find the estimated tons needed for your project.
