About this conversion
88 miles per hour is the single most famous number in the Back to the Future trilogy, it's the exact speed the DeLorean time machine needs to hit to activate time travel (alongside the equally famous 1.21 gigawatts the flux capacitor needs to draw). This converter turns that iconic 88 mph into whatever speed unit you actually think in.
1.21 gigawatts is a unit of power, not speed, so it can't share a single number line with mph, but for scale, 1.21 GW is roughly the output of a large power station, which is why Doc Brown needed a bolt of lightning (or, later, household garbage) to generate it.
Units supported: Miles/hour, kilometers/hour, meters/second, knots, and the time-travel speed benchmark (88 mph).
Source note: 88 mph and 1.21 gigawatts are both stated directly on-screen in Back to the Future (1985).
