FIGURE 5-0 Unit Conversion MATLAB App Front Panel - A-Z Tab.

The NIST Special Publication 811{30} includes an alphabetical list of conversions to SI units. Conversion factors are the mathematical multiplier or divisor and associated units that allow any compatible measurements to be converted from one system of units to another system of units (e.g., inches to centimeters or vice versa). From-units listed, except those preceded by an asterisk, are not to be used in NIST publications.

Figure 5-0 shows the Unit Converter MATLAB App Front Panel with the A-Z Tab selected. Unidirectional matrices were created and installed within this app to allow the user the ability to easily select via pull-down menus the desired conversion pair. Each of the Tabs available in the App is explored herein.

5.1 A TAB

The first Minor Tab under the A-Z Major Tab is the A Tab (see Figure 5.1-1). This example demonstrates the conversion of ampere hour (A*h) to coulomb (C). In this example, the amplitude of ampere hours is set equal to one (1.0). The conversion equation is shown in Example 5.1-1 {37}.
