Reporting a wrong result
The fastest way to get a calculation checked is to send the share link. Use “Copy share link” under the shopping list, paste it into your email and say which line looks wrong and what you expected. The link contains the whole project, so the result can be reproduced exactly.
Suggestions
Suggestions for new materials, package sizes, calculators or languages are welcome. Typical values from a manufacturer’s data sheet, with a link, are especially useful.
