Convert & Calculate
Units, currency & calculator
Free
Convert everyday units, calculate expressions, and check dated ECB currency reference rates in one app.
Convert everyday measurements and calculate without an account. Choose from nine unit categories, search units, save favorite categories and conversion pairs, and see equivalent values at a glance. Enter arithmetic directly in the amount field, including fractions and mixed feet/inches or pounds/ounces. The calculator includes a live result and recent calculations. Currency conversion uses dated European Central Bank reference rates, downloaded directly from the ECB and cached for offline use. Refresh rates when connected; the app shows the date of the data. Reference rates are estimates and may differ from transaction rates. Unit conversion and calculations work offline. Optional usage sharing is off by default, and bug reports or feature requests are sent only when you choose to submit them.
