The epic story of the invention of a global network of weights, scales, and instruments for measurement.

Millions of transactions each day depend on a reliable network of weights and measures. This network has been called a greater invention than the steam engine, comparable only to the development of the printing press.
Robert P. Crease traces the evolution of this international system from the use of flutes to measure distance in the dynasties of ancient China and figurines to weigh gold in West Africa to the creation of the French metric and British imperial systems. The former prevailed, with the United States one of three holdout nations. Into this captivating history Crease weaves stories of colorful individuals, including Thomas Jefferson, an advocate of the metric system, and American philosopher Charles S. Peirce, the first to tie the meter to the wavelength of light. Tracing the dynamic struggle for ultimate precision, World in the Balance demonstrates that measurement is both stranger and more integral to our lives than we ever suspected.

    The basic names—meter, liter (a cubic decimeter), and gram (defined as the weight of a cubic centimeter of pure water at the temperature of melting ice)—would be used to build a comprehensive nomenclature, with prefixes to denominate ten, hundred, and thousand, and tenth, hundredth, and thousandth
