Hassan Nawaz, Publisher.
Hassan Nawaz is an engineer (B.Sc. Electrical Engineering) who builds and publishes CubicYardMath. He is not a landscaping contractor. The figures come from landscape supplier spec sheets for weights per cubic yard and the volumes printed on bagged products, and each page names its sources. Every calculator is tested against worked examples before it goes live.

What I write here
I write and test every calculator on CubicYardMath, check each formula against the published standard or reference table it comes from, and update pages when those standards change.
