Summary

The United States names the metric system as the preferred way to measure things for trade and commerce. Federal agencies must, where it is economically practical, use the metric system for buying goods, giving grants, and other business activities by the end of fiscal year 1992, unless doing so is impractical or would cause big inefficiencies or lost markets (for example, when foreign competitors use non‑metric units). The government will also work to teach and explain the metric system through education and official publications. Traditional (non‑metric) units may still be used for non‑business activities.

(1)to designate the metric system of measurement as the preferred system of weights and measures for United States trade and commerce;

(3)to seek out ways to increase understanding of the metric system of measurement through educational information and guidance and in Government publications; and
(4)to permit the continued use of traditional systems of weights and measures in non-business activities.
