The Secretary of Commerce is directed to cause a complete set of all the weights and measures adopted as standards to be delivered to the governor of each State in the Union for the use of agricultural colleges in the States, respectively, which have received a grant of lands from the United States, and also one set of the same for the use of the Smithsonian Institution: Provided, That the cost of each set shall not exceed $200.

Such necessary repairs and adjustments shall be made to the standards furnished to the several States and Territories as may be requested by the governors thereof, and also to standard weights and measures that have been or may be supplied to United States customhouses and other offices of the United States under Act of Congress, when requested by the Secretary of Commerce.

The Secretary of Commerce is authorized and directed to furnish precise copies of standard weights and measures, bearing the seal of the National Institute of Standards and Technology and accompanied by a suitable certificate, to any State, Territory, or institution heretofore furnished with the same, upon application in writing by the governor in the case of a State or Territory, or by the official head in the case of an institution, setting forth that the copies of standards applied for are to replace similar ones heretofore furnished, in accordance with law, which have been lost or destroyed: Provided, That the applicant shall, before the said standards are delivered, first deposit with the Secretary of Commerce the amount of money necessary to defray all expenses incurred by the National Institute of Standards and Technology in furnishing the same, which amount shall be covered into the Treasury of the United States to the credit of miscellaneous receipts as soon as the weights or measures are delivered for transportation into the hands of such persons as are designated by the officers ordering the same.

It shall be lawful throughout the United States of America to employ the weights and measures of the metric system; and no contract or dealing, or pleading in any court, shall be deemed invalid or liable to objection because the weights or measures expressed or referred to therein are weights or measures of the metric system.

The metric system of measurement shall be defined as the International System of Units as established in 1960, and subsequently maintained, by the General Conference of Weights and Measures, and as interpreted or modified for the United States by the Secretary of Commerce.
