Weights, measures or weighing or measuring devices are defined to include all weights, scales, beams, measures of every kind, instruments and mechanical devices for weighing, or measuring, and any appliances and accessories connected with any or all such instruments. The federal government has adopted a standard for weights and measures which is adopted on a state-by-state basis. In states which adopt the federal standard, all contracts made within the state for any work to be done or for anything to be sold or delivered must be construed to have been according to the standard, unless the parties stipulate to the contrary.
Weights and measures regulatory professionals set standards and enforce uniform procedures to verify weight, volume, length or count, ensuring that consumers get the quantity that they pay for and that businesses sell the quantity that they advertise. Inspections may be conducted at such places as grocery stores and gas stations. Some of the items affected include home heating oil, fabrics, parking meters, and taxi fares.
