It's commonly quoted that the amount of electricity needed to power the DeLorean's time-travelling in Back to the Future is 1.21 Jigawatts. However, what Doc actually says is "One point twenty-one jigawatts", in other words 1 in the units place and 21 in the first decimal place. That is to say, (1 * 1) + (21 / 10) = 3.1 Jigawatts -- an error of nearly 200%.
