To model the equation that converts Celsius temperature to Fahrenheit

T= 9/5(_{F}T) + 32_{C}

First, consider the blocks needed to build the model:

A Ramp block to input the temperature signal, from the Sources library

A Constant block to define a constant of 32, also from the Sources library

A Gain block to multiply the input signal by 9/5, from the Math Operations library

A Sum block to add the two quantities, also from the Math Operations library

A Scope block to display the output, from the Sinks library

Next, gather the blocks into your model window.

Assign parameter values to the Gain and Constant blocks by opening
(double-clicking) each block and entering the appropriate value. Then,
click the **OK** button to apply the value and
close the dialog box.

Now, connect the blocks.

The Ramp block inputs Celsius temperature. Open that block and
change the **Initial output** parameter
to 0. The Gain block multiplies that temperature by the constant 9/5.
The Sum block adds the value 32 to the result and outputs the Fahrenheit
temperature.
