One knot (kn) is one nautical mile per hour. One mile per hour (mph) is one statute mile per hour. The international nautical mile is exactly 1,852 meters; the international statute mile is exactly 1,609.344 meters. The speed conversion follows the ratio of those mile lengths.
mph = knots × (1852 ÷ 1609.344)knots = mph ÷ (1852 ÷ 1609.344)km/h = knots × 1.852The factor 1852 ÷ 1609.344 ≈ 1.150779448 is the number of statute miles in one nautical mile.
