Units in Simulink

Unit specification and unit conversion functions for Simulink® signals

Simulink enables you to specify physical units as attributes on signals at the boundaries of model components. By specifying, controlling, and visualizing signal units, you can ensure the consistency of calculations across the various components of your model. For example, this added degree of consistency checking might be useful if you are integrating many separately developed components into a large, overall system model. To get started with units, see Unit Specification in Simulink Models.
