Page 29 - Used in assaying. The assay ton bears the same relation to the milligram that a ton of 2,000 pounds avoirdupois bears to the ounce troy; hence the weight in milligrams of precious metal obtained from one assay ton of ore gives directly the number of troy ounces to the net ton.
Page 4 - The essential features of the system were embodied in a report made to the French National Assembly by the Academy of Sciences in 1791. A number of other nations were invited to cooperate with France in establishing the new system, and Holland, Denmark...
Page 12 - When an equal-arm balance is used to compare an object with standards of mass ("weights"), the effects of variations in the acceleration of gravity are self-eliminating and need not be taken into account, but the apparent mass of the object is slightly different from the true mass because of the buoyant effects of the surrounding air. Mass can then be computed from apparent mass by applying a correction for air buoyancy. When a spring balance is used, an additional correction accounting for the local...

Page 4 - The liter is defined as the volume occupied, under standard conditions, by a quantity of pure water having a mass of 1 kilogram. This volume is very nearly equal to 1 000 cubic centimeters or 1 cubic decimeter; the actual metric equivalent iĦ.
Page 20 - The meter bars, however, continue in use as a standard for most types of measurements. In the metric system, designations of multiples and subdivisions of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo, meaning, respectively, 10, 100, and 1,000, and deci, centi, and mill!, meaning, respectively, one-tenth, onehundredth, and one-thousandth.
