📐 How Knot (kn) and mph Relate
In metrology, speed quantifies rate of change of position with respect to time ($L/T$). Within this domain, Knot (kn) and mph originate from Metric (km/h), imperial (mph), and nautical (knots). Standardized internationally by ICAO (aviation), IMO (maritime), and SI transport metrology.
Because both Knot and mph belong to the linear speed domain, conversion between them is strictly proportional. The exact conversion factor (1.15077845) guarantees zero precision drift across mathematical calculations.
