The NIST Constants Ontology

This graph defines terms for and contains the values and standard uncertainties of 324 physical constants taken from the NIST website: The NIST Reference on Constants, Units, and Uncertainty, at http://physics.nist.gov/cuu/index.html .

The NIST Constants Ontology defines both data and ontology schema and uses the namespace http://data.nasa.gov/qudt/owl/nist-constants# and the prefix nist for all internally defined resources.
