Measurement Standards

The Measurement Standards Program provides consumer protection and promotes equity and integrity in the marketplace. Both buyer and seller rely on accurate measurement and pricing during commercial transactions.

Through enforcement of the Colorado Measurement Standards Act, a large percentage of the commerce in Colorado is covered by Measurement Standards, also known as Weights and Measures.

The Measurement Standards Program establishes and enforces the method of sale for a given commodity when an existing practice does not promote value comparison.

The State Metrology Laboratory is the custodian of Colorado's official standards and provides metrology services to both public and private sectors. Mass, length, volume, time, frequency, and grain moisture standards are calibrated.
