Was having the same problem, then wondered: aren't their browser extensions which parse the text and convert units? Did a quick search but didn't find any - shouldn't be that hard though?

There's AutoConvert and EverythingMetric for Chrome. The automatic conversion is sometimes a bit annoying as there are edge cases.

Absolutely, and, living in the US, I can tell you a lot of mineral water bottles are packaged in metric units (1 or 1.5L bottles).

What would be the use? These are just rough guidelines.

If only there was a large corpus of searchable knowledge only a click away where the conversions could be determined.

Turning a 5 minute read into a 10 minute one.

It takes you as long to read the article as it does to google a simple conversion?

You have to do it multiple times since there is more than one value. Also include time for switching tabs etc, and then returning and working out where you were.

FWIW if you're on a Mac, Spotlight will do simple unit conversions, so you can just cmd-space and do it in the popup without having to leave the page.

That said yeah US units are absolutely brain-dead and confusing, how hard is it to put real units in parenthesis?

Multiply this by every single person who has to do this whole process.

Kind regards,
