Quantity and unit manager: unit system

Unit Systems

The Quantity and unit manager offers different systems of units measurement:

International system (official reference)

« US » system (the units most frequently used in the US zone)

By default, no units system is chosen, Each quantity has a unit attributed by Flux*. This unit always corresponds to the first unit of the proposed list, and it is this one which has the « Active » box checked by default.

Then the user has the option to configure the use of the Flux software by imposing a specific system of units (see the section below).

Note: *The units attributed by Flux (by default) are very close to the units of the international system.
