I took your advice and set my page preferences to show both English and metric units on Weather Underground and this is what it shows right now for Paris:

This makes me laugh even more as the person who programed the conversions has made even more funny errors.

We now have the pressure in inches of mercury (the english unit) as well as hectopascals (the metric unit.) which are correct but the next line shows the visibility to be 8000.0 statute miles, 12800 km!

I know, sometimes you can see 92 million SM when the sun is visible (not today, il fait naeugeux), but  they never measure 8000 SM visibility.

Look at the actual METAR report at the bottom and you will see the group "8000" which is the measured visibility in meters. The programmer apparently took this to mean 8000 SM.

LOL

And the cloud heights, (nauges) 1000 feet and 304 meters, why not an  even 300 meters? And more clouds at 3300 feet, 1005 meters, why not an even 1000 meters?

Yes, I'm more familiar with metric units but I'm aware that for
certain applications, like aviation, the English units are kept being
used. I don't know why in aviation they can't use 300m instead of
100ft. May be one fears that a change to metric would create a too
high risk.

So, if English units are the "decent" ones for you, why then you don't
click on the link "Page Preferences" at the top of wunderground's page
and adjust the units to be shown to those? Since the METAR are in
English units you would see the original data without conversion.

BTW, regarding English units: I noticed recently that the department
stores here in Istanbul indicate the power of air conditioners in BTU.
I guess that only a very, very small part of the population in this
country knows what this stands for.
