Report a calculator problem
Tell us the calculator name, the measurements and units you entered, the result shown, and what you expected instead. For weight estimates, mention the bulk density and whether it describes loose or compacted material. A page link is helpful.
Example: “On the Drain Rock Calculator I entered a 40 ft trench, 12 in wide and 18 in deep. I selected inches for the pipe diameter and expected a different gravel volume.”
