Sailing, aviation and marine weather report speed in knots, which converts to mph for everyday context.
Typical values: 0.5 kn is about 0.5754 mph, and 100 kn works out to roughly 115.0779 mph. Because the ratio is fixed at 1.1508, you can scale any amount linearly — doubling the knots doubles the miles per hour.
Road signs, aviation and sailing each use their own speed unit, so the same motion can be described several ways.
