Functions in app designer

Wondering how to put a function full of switch cases into the app designer so that when a varible is selected in the 'edit feild (numeric)' it does the set equation.

currently this is my function:

function y = UnitConversionsFunction(x, options)

%unit conversions

switch options

case 'c2f'%cel to fah

y=(x*9/5)+32;

case 'f2c'%fah to cel

y=(x-32)*5/9;

case 'mil2fo'%milliltres to fluid ounce

y= x/29.5735;

case 'fo2mil'%fluid ounce to millilitres

y= x*29.5735;

case 'l2p'%litre to pints

y= x*1.75975;

case 'p2l'%pints to litres

y= x/1.75975;

case 'l2g'%litres to gallons

y=x/4.54609;

case 'g2l'%gallons to litres

y= x*4.54609;

case 'kilj2kilc' %kiloj to kiloc

y=x/4.184;

case 'kilc2kilj'%kiloc to kiloj

y= 4.184*x;

case 'pas2psi' %pas to psi

y= x/6894.76;

case 'psi2pas' %psi to pas

y= x*6894.76;

otherwise

error ('please enter correct option')

end

end
