Automatically translates all sites from American/old British units to International System of units (SI/Metric) – adding converted unit in a bracket behind original units.
Example: 10 feet 🠚 10 feet【𝟯 𝗺】
Convenient for shopping, cooking, etc.
(You can also use Alt+M for manual conversion of the page)
Inch, Feet, Yard, Mile -> Metre (Meter)
Pound, Ounce, Stone -> Kilogram
Gallon, Quart, Pint, Fluid Ounces, Cups -> Litre (Liter)
mpg -> L/100 km
mph -> km/h
Fahrenheit -> Celsius/Kelvin
Area conversion for ft, yd, in, mi, both as “sq. ft” and “ft²” (must not be superscript); the same is for volume conversion.
Supports Amazon, Ikea, and other formats: 10″ x 20″ x 3″ will be converted and replaced with metric units
Combo units also supported: 1 ½″【𝟯,𝟴 𝗰𝗺】 or 2’−4″【𝟳𝟭 𝗰𝗺】
Features most possible ways these units are written with dashes, quotes, apostrophes, Unicode units, etc.
Toolbar button to turn extension ON/OFF globally
You can keep it off and just run when needed by pressing Alt+M
Permission to read page data is required to be able to change units.
Permission to storage is required to save settings.

It’s fairly good. The settings is a bit of a mess, and could need an overhaul. (For example, number formatting could be a dropdown giving: 1 234,5 / 1.234,5 / 1,234.5 / 1’234.5 as options)
It isn’t good with context. For example “## km (## mi)” is converted too when it shouldn’t.
It should work with context for “in”, such as “Dimensions: # in”, “# in by # in”, “# × # in”, “# ft # in”. Then the option for “in” should be options like “Convert # in: smart detection / always / never”.
awesome! finally don’t have to deal with those arbitrary units anymore!!!
Salvation
DA BEST THING !!!!! I like to look for foreign recipe online but the imperial system is such a pain in the *ss. Thanks to this plug in everything is automatically, instantly converted into the so much more convenient metric system. Love it <3
Does what it needs to!
works great – i have this on all my browsers now and it’s hard to go back! bookmark this for future use.
Excellent idea but it doesn’t seem to catch everything. For example “6-foot-8” and “6’8” don’t get converted, but “6-foot-8-inch”. It’s also a little bit inconsistent. Heights and lengths, if they get converted, get replaced. Weights get left alone and explained in brackets afterwards like:【141 kg】. The brackets are a good idea so you can see what has been changed. I’m finding now it’s changing things I’m reading to into an unpredictably mix of imperial-only, metric-only and sometimes both. As I said, great idea, but it needs to be developed a bit more to catch all of the various ways that Americans write imperial measurements and a consistent approach to replacement or addition would be good as well.
This is an amazing life-saver! THANK YOU FOR MAKING THIS!!!
Nice job! some it makes some mistakes from here and there but well the web is a messy place
Does the job very well!
I found a great engineering online forum based in the US. Since they use imperial units in most of the posts I was blind. This extension solved my problem and I can finally follow the discussion.
Another one that doesn’t work properly. Even with the watch mode enabled, it only converted the first line of a recipe and ignored everything afterwards.
Looks nice, but inaccurate for my needs (as a motoring journalist). Fuel consumption conversion (from MPG to L/100km) was out by a litre or more, and it was also unable to discern that ‘lb-ft’ is a measurement of torque, giving me instead a conversion for the ‘lb’ part of ‘lb-ft’ — which meant I was getting a weight measurement, not a torque measurement.
The second most useful extension I’ve ever used (after uBlock)
The best unit converter from all chrome extentions. Love it!
Automatically converted Amazon measurements to metric without losing the existing measurements.
