weights and measures. 



1 hhd. = 2 bbl. = 63 gal. = 252 qt. = 504 pt. 2,016 gi. 

The U. S. Gallon contains 231 cu. in. = .134 cu. ft., nearly, or 1 cu. ft. contains 7.481 gal. The following cylinders contain the given measures very closely:  


When water is at its maximum density, 1 cu. ft. weighs 62.425 lb. and 1 gallon weighs 8.345 lbs. For approximations, 1 cu. ft. of water is considered equal to 7½ gal., and 1 gal. as weighing 8⅓ lb. The British imperial gallon, both liquid and dry, contains 277.274 cu. in. = .16046 cu. ft., and is equivalent to the volumne of 10 lb of pure water at 62° F. To reduce British to U. S. Gallons, multiply by 1.2. Conversely, to convert U. S. into Britsh liquid gallons, divide by 1.2: or increase the number of gallons 1/5.
