Editorial policy
Order gravel short and you pay a second delivery fee. Order long and you own a pile of stone you cannot send back.
That is the whole reason CubicYardMath exists. We would rather show you one number you can trust, and exactly how we got it, than ten numbers you have to second-guess. Here is how we work.
We show our working
Our calculator pages show the formula behind the answer, so you can do the math on paper if you would rather. Where a result depends on published data, such as a standard size or a typical weight, we link the source, and we keep adding step-by-step worked examples. If our answer and yours disagree, one of us has made a mistake, and we want to know which.
We test before we publish
We check every material calculator against hand-worked jobs, like a 20 by 12 foot parking pad at 4 inches deep, and against the weights suppliers actually quote. Right now CubicYardMath has 13 calculators and 44 automatic checks. Each check is a hand-worked answer the calculator has to match exactly. They run every time the site is updated, and an update that breaks one does not go live.
Weights are typical, so we say so
A yard of crushed stone, topsoil or mulch weighs different amounts depending on moisture and fines. We use a typical supplier weight for each material, list every one on the material weight chart and add a waste allowance, so you order enough once.
Dates mean something
The "Updated" date on a page only changes when the page itself changes. We do not bump dates to look fresh.
Ads pay the bills, not the answers
CubicYardMath is free to use and is meant to be supported by advertising. Advertisers never see or influence our numbers, and we do not sell links, sponsored rankings or paid reviews.
Tell us when we are wrong
If a number looks off, send us the page and the value. Hassan Nawaz reads every message. Confirmed mistakes are fixed, the page date is updated, and if your note made a page better, we are grateful for it.
