## Long Ton Table

 16 ounces................................= 1 pound.........................lb. 112 pounds................................ = 1 hundredweight ......cwt. 20 cwt., or 2,240 lb.................= 1 ton...............................T.

## Troy Weight

 24 grains (gr.) ..........................= 1 pennyweight .........pwt. 20 pennyweights...................... = 1 ounce.........................oz. 12 ounces................................... = 1 pound.........................lb. 1 lb. = 12 oz. = 240 pwt. = 5,760 gr.

## Dry Measure

 2 pints (pt.) .............................= 1 quart........................qt. 8 quarts ...................................= 1 peck....................pk 4 pecks......................................= 1 bushel .......................bu. 1 bu. = 4 pk. = 32 qt.= 64 pt.

The U. S. struck bushel contains 2,150.42 cu. in. = 1.2444 cu. ft. Its dimension are, by law, 18i in. in diameter and 8 in. deep. The heaped bushel is equal to 1 1/4 struck bushels, the cone being 6 in. high. The dry gallon contains 268.8 cu. in., being 1/8 bu.

For approximations, the bushel may be taken at 1 1/4 cu. ft.; or a cubic foot may be considered 4/5 of a bushel.

The British bushel contains 2,218.19 cu. in. = 1.2837 cu. ft. = 1.032 U. S. bushels.

## Liquid Measure

 4 gills (gi.) ..........................= 1 pint ............................pt. 2 pints...............................................= 1 quart.................................qt 4 quarts................................... = 1 gallon .....................gal. 31 1/2 gallons...................................= 1 barrel...............................bbl 2 barrels, or 63 gallons ..........= 1 hogshead................hhd. lhhd. = 2bbl. = 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 7.480 gal. The following cylinders contain the given measures very closely:

 Diam. Height Diam. Height Gill............. 1 3/4 in. 3 in. Gallon ...... 7 in. 6 in. Pint ......... 3 1/2 in. 3 in. 8 gallons 14 in. 12 in. Quart ....... 3 1/2 in. 6 in. 10 gallons 14 in. 15 in.

With water at its maximum density weighing 62.425 lb. per cu. ft.), a gallon of pure water weighs 8.345 lb.

For approximations, 1 cu. ft. of water is considered equal to 7 1/2 gal., and 1 gal. as weighing 8 1/3 lb.

The British imperial gallon, both liquid and dry, contains 277.274 cu. in. = .16046 cu. ft., and is equivalent to the volume of 10 lb. of pure water at 62° F. To reduce U. S. to British liquid gallons, divide by 1.2. Conversely, to convert British into U. S. liquid gallons, multiply by 1.2; or, increase the number of gallons 1/5.
