MEAS109 - Fundamental Constants in Metrology
The international standard ISO/IEC 17025 "General Requirements for the Competence of Testing and Calibration Laboratories" allows for traceability to the SI units to be established through agreed upon values of natural physical constants. In this course we will survey some of the constants that can be used for this purpose.
- Introduction

- Pi - π
- Thermodynamic and Quantum Mechanical Constants
- Avogodro's Number - NA
- Boltzmann's Constant - k
- Universal Gas Constant - R
- Triple Point of Water -
- Stephan-Boltzmann Constant - σ
- Planck's Constant - h
- Planck's Constant divided by 2π
- ITS-90 fixed points
- Electrical Constants
- The elementary charge - e
- The Josephson Constant - Kj
- The von Klitzing Constant - RK
- Magnetic Permeability of vacuum - μ0
- Electric Permittivity of vacuum - ε0
