Knot (kn) is part of the Imperial / US Customary measurement system, while Feet per Second (ft/s) belongs to the Imperial / US Customary system. The difference matters because a recipe, blueprint, or technical spec written in imperial / us customary will not match measurements in imperial / us customary unless converted precisely. Mixing systems without conversion can lead to misjudging travel time on a road trip with wrong speed units.
