Units of Measurement

Use physical units, converting units, checking unit consistency and compatibility

Use and manipulate physical units of measurement. These units act as symbolic expressions and can be used with Symbolic Math Toolbox™ functions. You can verify unit dimensions, convert between units, and create your own custom units.
