Metrology, the scientific study of measurements having origins in the early 19th century, formed from the Greek metron ‘measure’ + -logy.
But wait! Depending upon your fields of endeavor…you certainly may be interested in measurements outside the realm of just weights! How about Radio Frequencies, Time, Dimensions, Pressures, Stress, Flatness, Voltage and Currents, Resistance…just a small sampling of items the values of which are all considered by Metrologists around the world.The United States established the National Bureau of Standards(known as NIST today) in 1901 to address scientists and industrialists needs to have an authoritative domestic measurement and standards laboratory providing standards for electricity, length, mass, temperature, light, and time, and created a system whereby they could transfer those standard values to the public.Uncertainty plagued U. S. markets at the turn of the 20th century. There were at least eight different definitions of a gallon, and four different definitions for a “foot” in use at the time. The NBS convened the first National Conference on Weights and Measuresto write model laws, distribute uniform standards, and provide training for inspectors which heretofore had been poorly trained and working with outmoded equipment.
