Fathers knew that a strong economy depends on fair trade, and
fair trade requires standards for weights and measures. The U.S.
Constitution gives the federal government the power to both coin
money and fix the standards of weights and measures.
In 1905, NIST established the National Conference on Weights and
Measures, a group of federal, state, and local officials. The
conference works to assure fairness in annual sales of more than
$4 trillion worth of goods and services from deli meats
to railroad freight to gasoline.
