AutoConvert is a free Chrome add-on developed by Aditya Bhaskar. It is a versatile tool that automatically converts units, currencies, and time zones when selected on a webpage.

With AutoConvert, you can easily convert metric units to imperial units and vice versa. For example, if you select "16 km", it will be converted to "10 mi". Time zones are also converted to your local time zone. Additionally, supported currencies are converted to your home currency.

The conversions are automatic and appear in a corner of the page as soon as you select any text containing convertible units. Alternatively, you can use the text box in the extension popup to manually convert values.

Please note that currency conversion is a premium feature and requires a purchase after the trial period. You can check if your currency is supported before making a purchase.

AutoConvert supports up to 6 conversions in a selection and unlimited conversions in the popup.

For more information and a list of supported units, currencies, and time zones, you can visit the developer's website.
