Contact and corrections

Plain Measure is a small, independent publication. We cannot give personal advice, but we do want to hear about mistakes.

Reporting an error

If you find a wrong statement, a guideline that has changed, a calculator result that looks wrong or a broken source link, please write to the publisher at the postal address shown on the legal notice page. Quote the page address and the sentence concerned and, if possible, the official source that shows the correct information. When a page is corrected, its "Updated" date changes.
