# An Introduction to the New SI

@article{Knotts2015AnIT, title={An Introduction to the New SI}, author={S M Knotts and Peter J. Mohr and William D. Phillips}, journal={The Physics Teacher}, year={2015}, volume={55}, pages={16-21} }

Plans are under way to redefine the International System of Units (SI) around 2018. The new SI specifies the values of certain physical constants to define units. This article explains the new SI in order to provide a resource for high school teachers as well as for advanced students already familiar with the pre-2018 SI.
