What People Usually Write In About

Most messages fall into a few categories: a conversion table entry that looked off, a request for additional reference points such as oven temperatures or medical readings, a display issue on a specific device, or a question about the formula itself. If you spotted a specific wrong number, tell us the exact value and where on the page you saw it, it helps us fix it faster.

How Fast We Reply

This is a small, independently run tool rather than a large support team. Expect a reply within a day or two. If a week passes with no response, feel free to send a follow up, sometimes emails end up in spam.
