coulomb.units

Accepted historic SI metric units

Selection of units from the following table, along with other commonly used "metric" units.

• https://en.wikipedia.org/wiki/International_System_of_Units#Non-SI_units_accepted_for_use_with_SI

Time units are defined in coulomb.units.time. Degrees Celsius are defined in coulomb.units.temperature.

A selection of physical constants.

Constants are as as defined in the following table:

• https://en.wikipedia.org/wiki/List_of_physical_constants

All units tagged as either "universal" or "frequently-used" in this table are defined. Other constant definitions can be included on request.

Units of information

These definitions use byte as the base unit, and therefore may be thought of as "storage centric" as opposed to information centric:

• https://en.wikipedia.org/wiki/Shannon_(unit)

or physics centric:

• https://en.wikipedia.org/wiki/Nat_(unit)#Entropy

For example in physics a nat is unitless, where in these definitions it is a derived unit of byte.
