It’s great fun especially when you’re trying to work out how fuel efficient your car has been when your tank and fuel pump is in litres and the fuel efficiency is in miles per gallon.
Oh and you’ll have a jolly time following a recipe from more than 20 years ago trying to remember what the hell “Gas Mark 4” is in centigrade for fan or convection ovens.
Oh and my personal favourite for the industry I’m in: when designing a PCB your component sizes will use imperial codes, your wire diameters will be in AWG, your track widths and PCB dimensions will be in millimetres, but your copper thicknesses will be in ounces despite the final weight for the assembly will be in grams.
Bear in mind that the gallon we use is different from the US gallon, too:
a UK gallon is eight (imperial) pints of 20 fluid ounces, so 4.54 litres
a US gallon is 231 cubic inches, so 3.79 litres
The reason that I thought American car fuel economy was so terrible as a child is partly because UK mpg is +20% on US mpg for the same car on the same fuel. But also, because American car fuel economy is so terrible.
May I present to you, how to measure like a Brit

Not milli-inches? Is this a UK thing or have PCB design evolve since I last touched it?
Anyway, milli-inches is one of the funniest unities I’ve used.
We call them thou.
Yeah, thou is industry standard. Never heard of mili inches

Brits also think our gasoline is crappier because we use a different calculation for octane, (R+M)/2 instead of RON.
So 90 RON is actually 85.9 in the US. And in most of the country the minimum is 87 (R+M)/2.
93 Premium is like 98 RON. And race gas 100 is like 105 RON.
To be fair though, your petrol is still insanely cheap compared to the UK and Europe.
US freedom is made from cheap gas.
I thought it was the right to keep a bear’s forelegs
