The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. SI use in product design, manufacturing, marketing, and labeling is essential for United States industry's success in the global marketplace. SI measurement system familiarity and fluency must be developed along the Science, Technology, Engineering, Arts, and Mathematics (STEAM) career pipeline to produce an U.S. engineering workforce with this essential 21st century skill.
Become familiar with SI units, develop measurement quantity reference points, and learn more about SI basics! Teachers are encouraged to explore and use these materials to support their STEAM curriculum and classroom measurement science.
