I'm perplexed by the question. I guess this is Kia's way of trying to offer something equivalent to mpg. In Canada we use km, so our readout is kWh/100km. Silly me, but I just assumed you'd get the equivalent with miles. If Wh/mi isn't available and you can live with the quick math (100km = 62 mi), maybe kWh/100km might be an available option.
