tl;dr: miles/kwh converter Since I got the Model 3, I've been frustrated by the Wh/Mile display. Living with a Leaf since 2012, and living with MPG and the concept of "higher is better" my entire life, the whole idea of Wh/Mile and "lower is better" is completely nutty to me. Maybe the bulk of Tesla owners with an engineering background have just thrown up their hands and said "eh, well, it works" and perhaps came from a bigger conversion of gas->electric, but I'm... I'm electric->electric and it's not going so smoothly. To my shock and frustration, there seem to be no conversion utilities online, anywhere readily accessible. Google can't convert it, WolframAlpha can convert it but it has to think really hard about it, and there's some painfully awful interface at Aqua-Calc that functions like a slide-rule (go ahead, take the number you have, adjust the table's range to match what you have, then look your number up in the table)... How about a simple website with a single function - input and output? Done. miles/kwh converter Now there's one less thing you can't Google.
