Welcome

The Western Weights and Measures Association (WWMA) is proud to be comprised of the following States: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.

Tare at Check Stand:  For packaged or bagged items like fresh produce or bulk coffee that are weighed at the check stand, compare the displayed weight on the scale to the net weight on the sales receipt.  The weight on the receipt should be slightly less if the system properly deducted the weight of the packaging material.  Contact your weights and measures authority with questions or concerns.
