Examples of Knot in a sentence
"When the wind picks up, this bad boy can go 25 knots."
"Using knots to measure speed seems strange until you're on the open sea."
Not to be confused with that other nautical mile, which measures distance, a knot measures speed and clocks in at 1.15 miles per hour. Maritime terminology isn't quite as common as it was when intrepid explorers were sailing the high seas, but "knot" has persisted — even if some would-be sailors use it incorrectly more often than not.
