Page 3 - Some confusion always arises as to the difference between density and specific gravity. Specific gravity is the ratio of the density of a substance to the density of a selected substance, usually water, under prescribed conditions.
Page 7 - a measure." The physical standard representing the meter was to be constructed so that it would equal one ten-millionth of the distance from the north pole to the equator along the meridian of the earth running near Dunkirk in France and Barcelona in Spain. The metric unit of mass, called the gram...
