But these quaint ye olde worlde English people don't know how far an inch, foot or yard is. Those measurements are just not used in everyday life, except for when describing how tall someone is, or the car only made it through the gap with inches to spare, or the shop is 100yards down the road. They couldn't actually tell you how many of each unit is in the other. They are just used as descriptive words not actual accurate measurements.
I do know my marathons measured in miles or kilometers though, and I do know how many meters to a mile. Speed has to be in miles, distance travelled in a car has to be in miles, distance that you throw a ball has to be in meters. Liquids that you drink with up to 7ish% alcohol have to be in imperial, liquids with alcohol content greater than that is in metric. Food is in metric (although until I had medical reasons for needing to know food weights I didn't really care as long as my plate was full).
Unless you are Nasa and get your measurement units mixed up, which they did a couple of years ago, then it really doesn't matter. The imperial units are all far better words for using for describing how far, fast or big something is. The metric ones are easier for counting with. But it's perfectly possible to get along using a mix of both and changing whenever the situation requires it.
