NIST Handbook 130, Chapter II. Uniformity of Laws and Regulations provide a listing of states and the various laws and regulations that they adopt.

Chapter III, Uniform Laws describes the many uniform laws states adopt including Section 7, Requirements for Unit Pricing; Section 15, Misrepresentation of Pricing; Section 22, Civil Penalties; and Section 23, Criminal Penalties..

It should also be noted that Chapter IV, Section C. Uniform Unit Pricing Regulation allows for either Metric or customary units to be used. This complements the Fair Packaging and Labeling Act (FPLA), which requires packages to have both metric and customary units net content labeling. The FPLA applies to products that are regulated by the Food and Drug Administration (FDA). The decision to provide unit price information in metric rests with retailers.  Uniform Unit Pricing Regulations apply only when stores voluntarily provide unit pricing information.  The unit of measure chosen must be consistent across like items within the category.
