Contact and corrections

Yard & Gallon is edited by Erdi Doğan. Email hello@yardandgallon.com about errors, outdated product numbers, a source that says something different from the page, or a calculator that gives a result you think is wrong.

Reporting an error

• The page address.
• What you typed into the calculator and what it showed (or the sentence that is wrong).
• If you can, the source that shows the right number, such as the product's data sheet or the code section.

We check the report against the source, correct the page if needed, and update its date.

What we cannot do

We cannot review plans, approve a design or tell you whether a project passes inspection. For that, ask your local building department or a licensed contractor.
