    Capacity: 1,728 cubic inches = 1 cubic foot. 27 cubic feet = i cubic yard. 1 litre = 1 cubic decimetre = 1,000 cubic centimetres = 35*3 fluid ounces = 6i cubic inches = o*22 gallon= 17617 pints. 1 cubic foot = 6‘23 gallons= 1,728 cubic inches. 1 gallon=434 litres = 276'94 cubic inches. At 40 C., or 39‘2° F. (the maximum density point of water), 1 cubic foot of water =1,000 fluid ounces. Weight: 1 cubic centimetre of distilled water at 40 C., or 39‘2° F., weighs 1 gramme = 1,000 milligrammes. 1 litre of water weighs 1,000 grammes =r kilo- gramme. 1 gallon of water weighs 70,000 grains =10 lbs. (Avoir.). 1 cubic foot of water=6f25 lbs. 1 gramme = 15-432 grains. 1 ounce (Avoir.) = 437-5 grains. 1 ounce (Troy) = 480 grains. 1 ton = 2,240 lbs. 1 lb (Avoir.) = 453-6 grammes. 1 kilogramme = 2-2046 lbs. 1 minim weighs 0-91 grain of water. 1 fluid ounce weighs 437-5 grains of water. 1 lb. (Troy) = 5,760 grains. 1 lb. (Avoir.) = 7,000 grains. By apothecaries’ weight, 8 drachms=i ounce = 437-5 grains; therefore, 1 drachm = 547 grains, not 60
