Found a bug, have a suggestion for a calculator that doesn't exist yet, or spotted something that looks wrong on an existing one? Reach out any time:

This is a small, independently-run site, so replies aren't instant — but every message gets read. Bug reports and correction requests are especially welcome. A calculator that gives a wrong answer is the one thing this site can't afford to get wrong.
