Yes, and this held true in the comparison of nautical miles to land miles (six nautical miles equal seven statute miles). But the statute mile is the same in the United States and England--5280 feet (the nautical mile is 6076 feet). The Roman mile was 5000 feet--but in the reign of Elizabeth, Parliament established the statute mile at 5280 feet (1760 yards), because the customary mile of 5000 feet could not be divided by yards (three feet), rods (sixteen and one half feet) or furlongs (660 feet) to produce a whole number. So standardizing the mile at 5280 feet was rather clever.
What is more interesting is the difference in other measurements, which can constitute a "peeve." U.S. Standard, or Customary, and Imperial (England and elsewhere) differ quite a bit in measures of volume. The Imperial ounce is larger, so that five Imperial ounces equal six U.S. Standard ounces. That can be a blessing for the dipsomaniac, though--an Imperial pint is the equivalent of 20 U.S. fluid ounces, or 25% larger than a U.S. Standard pint. The drunkard can delude himself that he's getting more bang for his buck.
I suspect that U.S. Customary measures of volume were, like "daylight savings time," adopted to the benefit of retail merchants. The Imperial gallon holds five U.S. Standard quarts, not four. In the United States, it is common to sell "fifths" when selling spiritous liquors. If that were a fifth of an Imperial gallon, you'd simply have a quart. But a fifth of a U.S. Standard gallon only yields somewhat more than 25 ounces, rather than 32.
The boys who made rum and corn whiskey, at any rate, made out like bandits on this.
Nevertheless, in the spirit of stubborn contrarity, i favor a system which is neither metric, nor "Imperial." It's nice to be different, and to have something to grouse about at the same time.
