This calculator estimates the volume and weight of material needed for roadway construction based on the dimensions you provide and the selected material type.
Volume Calculation
The volume is calculated using the formula for a rectangular prism:
Weight Calculation
The weight is calculated by multiplying the volume by the material density:
Unit Conversions
The calculator automatically handles conversions between imperial and metric units:
- 1 foot = 0.3048 meters
- 1 cubic yard = 0.764555 cubic meters
- 1 pound = 0.453592 kilograms
- 1 ton (US) = 2000 pounds
If you have irregular shapes, you may need to break them down into a set of regular shapes, then add up the parts. For example, if you have a lot in the shape of an “H” or an “L”, break it down to different sections, calculate each, then add the amounts together. As an alternative, you can enter your total area if you know it from your own calculations.
