Oh where to start. Often on the motorway I will find a vehicle in front of me toddling along the motorway around 44mph on a 70mph motorway and wonder why? Then I think again, 44mph equates to roughly 70kmph. It would appear that some foreign travellers have not converted from KMP to MPH hence the difference when they see a "70" speed sign.Strange lot, you Brits. (I know, so are we Yanks.)
Now that you mention it, I do seem to remember speed limit signs in the UK strangely being in MPH. Which can be extremely confusing to someone (like me) who was living in Continental Europe at the time. This...

..means 50 km/h; while this, in contrast...

...means 50 MPH?
Especially to someone who maybe doesn't realize that you guys still use miles...?
I'm a bit the same way... In the U.S. military we, of course, use metric to measure ground distance or range... Like that enemy tank is at a range of one-eight-hundred meters (1,800 m). Or, of course, "klicks" as a slang for kilometers. So I can visualize (long) distances in either miles or kilometers. Or car speeds, to a lesser degree, having lived in Europe so long.
But short distances? It's gotta be feet. For scuba diving, I can immediately visualize what a depth of 30 ft means. Not so much 18 meters...
I prefer the ready concept of 1 1/2 x KPH = speed in MPH ie 44 x 1.5 = 63. If anyone uses that quick calculation they should roughly be in line with UK speed limits.
Again as an example 30mph x 1.5 = 45kmph.
Drat cat on KB and Im just back from the caravan, gotta go quick.
