power and voltage unit of GUI is not working

i have made a GUI for Wind Plant Simulink system. and i have change the power and voltage units from MW and KV to W and V. but i didn't see a different result from what it was. the resul for voltages was 0,009 and power was 0,33 but it still like that eventhough i change the power and voltages unit in preferences of GUI.

thank you for advance

Mb in formula used U^2. Lets try with R=1. P=(U^2)/R

When U = 1 KV = 1000V => P = 1MW

When U = 1 V = 1V => P = 1W

Input "1" = Ouput "1" in both cases
