The toolkit can use data expressed in either US Customary of SI Metric units. A project's unit system depends on the unit system used for its choice of flow units. If the @ref EN_open function is used to supply data to a project from an Input File then its flow units are set in the @ref OptionsPage section of the file. If the @ref EN_init function is used to initialize a project then the choice of flow units is the fourth argument to the function. The following table lists the units used to express the various parameters in an EPANET model.

If the @ref EN_init function is used to initialize a project then the choice of flow units is the fourth argument to the function. An exception to this convention is pressure whose units can be expressed in either US or SI units. The following table lists the units used to express the various parameters in an EPANET model.
