I really hope not and the op is on the wind up. I wish we’d get rid of this half and half system and put imperial in museums where it belongs.
If you think about it it makes no sense. Why is there 12inchs in a foot, but 14 pounds in a stone? Where does 3 feet in a yard come from?!
At least metric makes sense everything is 10, 100 or 1000. 1000grams is 1kilogram, 1000m is 1kilometer.
Metric is a far better method of measurement. A metric ton of distilled water is exactly 1m^3 which allows for the quick and accurate conversion between length and mass then the onward scaling at factors of 10 or 1,000.
Much more convenient for engineering calculations.
