A note of interest - it's at the pint that American and Imperial measures diverge. The Imperial pint is 20 oz - two and a half cups. From there, the quart is 2 pints = 5 cups = 40 oz, the gallon is 4 quarts = 8 pints = 20 cups = 160 oz. That's why Canadian gallons are larger than American gallons by a ratio of 5 to 4. on January 16, 2006 08:25 PM
