§ 177. Authorized systems of weights and measures; basic units. 1. The
metric system of weights and measures and the system of weights and
measures in customary use in the United States are jointly recognized,
and either system shall be used for all commercial purposes within the
state. However, the International Metric System ("SI"), as defined in
the Metric Conversion Act of nineteen hundred seventy-five (Public Law
94-168) and as such definition may hereafter be amended, is hereby
adopted as the preferred system within the state.

2. The definitions of basic units of weight and measure, the tables of
weight and measure, and weights and measures equivalents as published by
the national bureau of standards or its successor organization, the
national institute of standards and technology, of the United States
department of commerce are recognized and shall govern weighing and
measuring equipment and transactions in the state.
