What to write to us about

Tell us if a result looks wrong. Include the shape, the measurements, the depth and the unit you chose, and what you expected instead. That lets us repeat your numbers and check them against the formulas.

We also welcome ideas for materials or unit conversions the calculators should cover.

What we cannot do

We are not a gravel supplier and cannot give you a quote or arrange delivery. For prices and exact weights, ask a local quarry or landscape supplier. Read how we handle your data in the privacy policy.
