liquid measure
4 gills (gi.)
=
1 pint pt.
2 pints
=
1 quart qt.
4 quarts
=
1 gallon gal.
31½ gallons
=
1 barrel bbl
2 barrels, or 63 gallons
=
1 hogshead hhd
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:
  Diam.   Height.     Diam.   Height.
gill 1¾ in.   3 in. gallon 7 in.   6 in.
pint 3½ in.   3 in. 8 gallons 14 in.   12 in.
quart 3½ in.   6 in 10 gallons 14 in.   15 in.
 

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.
