The unit UNIVCONST offers a collection of universal constants and conversion factors covering

• Astronomy,
• Chemistry,
• Common Measurement Units,
• Electromagnetism,
• Math, and
• Physics.

All the constants are based on the SI system, however some of the constants are declared twice if this constant is often used with different units, e.g. the Planck constant is given in Js (SI units) and in eVs (non-SI units). Please have a look into the help pages for further details.
