Abstract

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

The namespace prefix for resources in this ontology is: constant

The vocabulary graph is available as: Turtle
