About UnitFlip

UnitFlip is a small, free tool for converting between metric and imperial (and US customary) units. It was built to do one job well: give you an instant, accurate conversion without asking for an account, a payment, or your data.

Everything happens in your browser using standard, internationally-defined conversion factors — your input is never sent to a server or stored anywhere. Covers length, weight, volume, and temperature, the categories people look up most.

UnitFlip is supported by ads shown alongside the tool, which keeps it free to use with no limits. It's one of a growing set of small tools at Laborilo.
