What! No BSF?
Special points will also be issued for BA.
I could include "Lucas threads" & BSP, but they are thread types  so don't directly count!

Yes, but the Metric units were the dreaded "black sheep" of the Metric System----cm!! :scared:

The Metrication Board would turn over in their collective grave! ;D

I suppose stating power in kW would make your car look 25% weaker compared to horsepower. But when you use CV? Instant 1.4% increase in number of units vs horsepower.

In the 1800's the average person didn't know how to do math or use an abacus. And riding your horse to the nearest guy with a victorian mechanical calculator might take awhile. We don't need to worry about this, anymore.

Example from BMW Portuguese Website:



There you also see the l/100km fuel consumption and the g/km related with the CO2 emissions.

Now I'm wondering about recipes. In america, we add a half cup of chopped celery, a teaspoon of vinegar, and a pinch of salt. In EU, you would add 100mL of chopped celery, 5mL vinegar, and 2 grams of salt?

I think we're talking about units used in industrial and commercial environments. Units used in recipes are essentially informal. But when necessary they are given in metric:

But a cup and a teaspoon at least are actual units of measurement, here. Not so sure of a pinch, though.

Same over here! So the problem has already been solved and we can all stop worrying about it!

I think the important thing is that where it's important, people use.... units. It doesn't matter what they are, as long as they are using them. When a pilot calculates how many "fuels" he needs to travel "distance," he needs to use units. Lb's, kg's, liters, w/e, so long as he is using units. If he memorizes 200 distances per fuels, and goes by that, he's an idiot. It's an education problem when that gets screwed up.
