About USMAAbout SIFor teachersBasicsJoin USMAMetric WeekMetric TodayPosterSuppliesSI GuideContact us

The US Metric Association (USMA), Inc., is a national non-profit organization that was founded in 1916. USMA advocates completing the US conversion to the International System of Units, known by the abbreviation SI (ess-eye) and also called the metric system. The process of changing measurement units to the metric system is called metric transition or metrication.

Among other things, this site contains information about the metric system, with some specifically designed for educators, as well as information about USMA and links to other selected metric sites.

Weights and Measures Week

1 - 7 March 2015

Weights and Measures: On the Path to Tomorrow

See the National Conference on Weights and Measures (NCWM) press release (MS Word document) for more information.

See also USMA's list of Metric events and anniversaries.

If you live in New York State:

New York State is the only US jurisdiction that has not yet adopted the 1999 amendment to the Uniform Packaging and Labeling Regulation (UPLR) that permits the option of eliminating non-metric units from labels of products not regulated by the federal Fair Packaging and Labeling Act (FPLA). Please contact USMA's PR Director if you are willing to help with this cause.

Is Your Company or Organization Going Metric?
We'd Like to Know

Perhaps your hospital is changing over to measuring patients' height and weight in metric units only, or your company's product line is going hard metric. We'd be very interested in the how and the why. And, with your permission, we'll tell your story in our newsletter, Metric Today. Please contact USMA.

To be found in the 2015 March/April issue of Metric Today:
  • How does metrication affect rubber hoses?
  • What's the best way to do unit pricing?
  • How should you weigh your dog?
  • Are there any metric American rocket launches?
(PDFs of the last three issues are available for USMA members. Contact the USMA Webmaster for access.)
