Step 1 : Introduction to the question "In the movie "Back to the Future", how much power does the DeLorean time machine need?"
The DeLorean time machine is a fictional automobile-based time travel vehicle featured in the Back to the Future franchise. After entering a target date, the operator accelerates the car to 88 miles per hour, which activates the flux capacitor. The time machine is electric and requires a power input of 1.21 gigawatts to operate. The power required is pronounced in the film as one point twenty-one "jigowatts". While the closed-captioning spells the word as it appears in the script, jigowatt, the actual spelling matches the standard prefix and the term for power of "one billion watts": gigawatt. The director thought it was pronounced this way because that was how a scientific adviser for the film pronounced it.
