Get in touch

Found a wrong number, want a new unit added, or just have feedback? We’d love to hear it.

A few things that help us help you faster:

• Corrections: tell us the exact conversion (e.g. “50 miles to km”), what you got, and what you expected.
• Bugs: note your device and browser, and what you tapped just before it happened.
• Requests: the unit, category or feature you’d like to see.

We’re a small, free project, so replies may take a little time — but every message is read.
