Section 126
SEC. 126. Weights and measures of metric system alone legal; exception in case of lumber.—Save in the purchase and sale of manufactured lumber the use of other weights and measures than those of the metric system shall not be legal, and said system, with its recognized scales, shall be used in all contracts, deeds, and other instruments publicly and officially attested, and in all official documents; and subject to the same exception only weights and measures of the metric system shall be officially sealed and licensed. In the purchase and sale of manufactured lumber the English system of measures may be employed; and in ordering commodities or articles from abroad such weights and foreign orders, measures may be employed as are commonly used in the country to which the order is sent or from which the goods are shipped.
