Every day, Americans make purchase decisions - at the grocery store, the gas pump, filling the propane bottle for their RV, or ordering a delivery of home heating oil. These diverse "daily necessities" have one common ingredient: the trust you can have that everything you weigh, pump or measure is accurate because of a national weights and measures program.

It is the National Conference on Weights and Measures (NCWM) and your state weights and measures inspectors that ensure a reliable system - providing confidence that you will get what you pay for.
