The Fundamental Constants Data Center at NIST is dedicated to advancing the understanding of fundamental physical and chemical constants. The center, part of NIST’s Physical Measurement Laboratory and Quantum Measurement Division, collects and analyzes data from various sources to evaluate these constants periodically. It also contributes to the development of the International System of Units (SI), ensuring its accuracy and consistency for scientific research and technological advancements. The center supports research through the Precision Measurements Grants Program, which funds experiments to refine knowledge of fundamental constants and improve measurement accuracy.
