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.

  • (2021-04-29) Adrian Sieber: Finally no more archaic units 😁
  • (2021-04-19) Jamie Cook: Great extension but I would have preferred an option to put the metric units in the text and have the original units either in brackets or removed completely.
  • (2021-03-03) Liggliluff: 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".
  • (2021-02-18) patrick weber: awesome! finally don't have to deal with those arbitrary units anymore!!!
  • (2021-02-09) Hugh O'Brien: Salvation
  • (2021-01-02) Jean-Philippe Dégeorges: 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
  • (2020-12-28) Nathan Maingard: Does what it needs to!
  • (2020-11-15) Lilian Lee: works great - i have this on all my browsers now and it's hard to go back! bookmark this for future use.
  • (2020-08-22) Benjamin Pyke: 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.
  • (2020-03-10) Thale Celicia Anker Feiring: This is an amazing life-saver! THANK YOU FOR MAKING THIS!!!
  • (2019-12-14) Samuel Franklin: Nice job! some it makes some mistakes from here and there but well the web is a messy place
  • (2019-06-20) Dmitry Gurovich: Does the job very well!
  • (2019-03-13) Edin: 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.
  • (2019-02-20) Great, useful app. We shouldn't have to convert units at all in the modern day, but this app works fine for now.
  • (2019-02-04) Matt Fletcher: 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.
  • (2019-01-19) I was mostly wanting this to convert the built in distance on Google maps without having to manually change units. It doesn't appear to do that, although it works fine for static distances/measurements displayed on webpages. Just not what I was looking for.
  • (2018-12-15) Mike Stevens: 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.
  • (2018-11-12) Esen S: The second most useful extension I've ever used (after uBlock)
  • (2018-11-06) Michał Onoszko: The best unit converter from all chrome extentions. Love it!
  • (2018-05-02) Waheed Alsayer: Automatically converted Amazon measurements to metric without losing the existing measurements.

Latest issues

  • (2021-04-26, v:3.4) Bård Ræstad: Overzealous quotation marks
    The plugin works great most of the time, but it could be smarter about when it translates inches to cm. From what I can tell, it always translates inches to cm when it registers numbers followed by quotation marks, even when there is a space between. But when it doesn't check the context of this input, it gives some funny results, as numbers followed by quotation marks aren't always inches. For example, this is the original title of a YouTube video: M12 "Warthog" Force Application Vehicle | Halo With the plugin activated, it's changed to this: M12 " (30 cm)˜Warthog" Force Application Vehicle | Halo As any human can tell, there were not actually any inches that needed translation in that title. I suspect that a simple check of what follows the quotation mark should reduce unnecessary translations considerably. Chances are that if what follows is a letter, number or special symbol, it's something in quotes following a number. If it's a space, break, punctuation marks or end of the text, it's inches that should be translated. Is this check possible to implement? Or alternatively, are there other ways to reduce unnecessary translations?
  • (2021-02-03, v:3.4) Cybele Nader: No tbps?
    I love the idea for the app and actually came looking for it. However it's not perfect. I see tablespoons aren't converted, and that's fine for liquids but when I get something like 3 tbsp of butter, that's super annoying and I'd have to do the thing that I'm trying to avoid which is open a new tab to convert manually on Google. Also it doesn't seem to work on everything. Like on one website it says 145 F for temperature and it doesn't seem to convert any of it. Same issue with another website that says 400 degrees although I would imagine that would be trickier to convert since it doesn't mention whether it's F or C (but it's obviously F). I think that's mainly it. Great extension nonetheless.
  • (2020-05-14, v:3.4) Canay Altinoz: all good but
    All good thank you. But in grainfather.com 's recipes section its not working
  • (2019-07-16, v:2.8) Tom Christoffersen: A few suggested improvements
    Hi, First off - great plugin, already rated 5 stars! Although I found some small issues that might improve the plugin: When a website is showing units in a range, say 60-80°F, it will only convert the last number as such: 60-80°F (27 °C)˜. Perhaps make it detect and convert the range? Some sites already show conversions behind the original unit, so now the plugin makes the conversion again and the result is a double conversion. So from the site linked below, 5-15°C (41-59°F) becomes 5-15°C (41-59°F (15 °C)˜ ) I understand this one might be hard to fix, and it doesn't really bother me. I noticed both these issues appeared on this site, under "Ongoing Care": https://www.rhs.org.uk/plants/popular/cordyline/growing-guide
  • (2018-07-03, v:2.3) Waheed Alsayer: Currency Converter
    Hi, I love the extension. How about making one for currency conversion, where I choose a a specific currency and it is updated daily and shows whenever a $ or e euro sign shows.
  • (2018-05-13, v:2.3) George SC: Bug?
    Hi, not exactly sure but seems your extension is messing up writing on files, like, In gmail I start writing Hi, and end up with Ih, the cursor jumps around in the first letter, I have disabled you adddon since was the last one I added in a long time and it's back to normal now. Hope you can fix it, love your extension othrwise Cheers
