Automatically converts values from other units, currencies and time zones
AutoConvert converts units, time zones and currencies, when you select them on a webpage.
Selecting metric units (e.g. 16 km) converts them to the imperial units (e.g. 10 mi), and vice versa (10 inch to 25 cm).
Time zones are converted to the detected local time zone.
Supported currencies are converted to your home currencies.
Conversions are automattic, and appear in a corner of the page as soon as you select any text containing convertible units.
Alternatively, convert any values by using the text box in the extension popup (press the extension button in the toolbar).
A list of supported units, currencies and time zones is available here: https://updatenotes.blog/autoconvert-list-of-supported-units-time-zones-and-currencies/
** Currency conversion is a premium feature, and requires a purchase after the trial period. Please check if your currency is supported before purchasing.
* Converts up to 6 values in a selection. Unlimited conversions in popup.
