UNITS OF MEASUREMENT
IrrigatePlus can compute using units in the International System (IS) or in the US System (US).
The unit system selected to be used for Flow determine whether the other magnitudes of the
project will be expressed in US Customary untis (US) or in metric units (IS). That is, when
selecting flow units in LPS, LPM, MLD, M
International System (IS). If, on the other hand, the selected flow units are in CFS, GPM, AFD,
MGD or IMGD, the US System will be used.
To change the flow units we can open the viewer located at the top

UNITS OF MEASUREMENT
Note: It is recommended to set the coordinates for the workspace immediately after creating a
new project, since the units of measurement might differ from those used to measure the length
of pipes.
