Everything Metric (Auto Unit Converter) is a handy Chrome extension that automatically converts American or Imperial units to the International System of Units (SI/Metric) across websites. It appends metric equivalents in brackets right after the original USC units to make reading measurements easy and intuitive.

Ideal for online shopping, cooking, or any browsing where measurements appear, this tool converts length (inch, feet, yards, miles), weight (pounds, ounces, stones), volume (gallons, quarts, pints, cups), speed (mph), fuel efficiency (mpg), and temperature (Fahrenheit) to their metric counterparts, such as meters, kilograms, liters, km/h, L/100km, and Celsius. It also supports area and volume conversions with proper unit notation.

The extension offers a toolbar button to toggle the conversion globally and a shortcut (Alt+M) to trigger conversion on-demand. Users can customize settings via the options page. Being open-source, it welcomes contributions and feedback.
