Weights and Measures division
We ensure equity in the marketplace through our Weights and Measures programs. This includes verifying:
- Consumers are being charged the lowest advertised or posted price for items at any store using a Point of Sale system (bar code readers, scanners, or price look-up systems).
- Packaged commodities contain the amount stated on the label.
- Gas stations are providing the correct amount of fuel (a gallon is actually a gallon).
- Free Air and Water is available at gas stations.
- Taxi meters are accurately calculating the fare.
- Propane dispensers are delivering the correct amount of Liquid Propane Gas (LPG).
- Scales used at grocery stores, recycle centers, and other locations around the county are accurate within the tolerances set by the Department of Food and Agriculture, Division of Measurement Standards (DMS).
- Devices of all types used for commercial purposes in Marin County are approved for use by DMS prior to being put into service.
