That would make it 2 orders of magnitude by that method. Happy to accept that it's 3 orders of magnitude by the N=a*10^b method though. Either way, it's definitely not one.
- m463 6y agoI think the whole point of orders of magnitude is to be a back-of-the-napkin estimation of what's what. "a new car is an order of magnitude difference in price compared to a used car" is appropriate even if a new car is 40k and a used car is 5k Electric cars have two orders of magnitude less energy storage than gasoline cars, but newer ones are only one order of magnitude.
