Knots to kilometers per hour converter
Convert knots to kilometers per hour with an editable calculator, worked example, formula and reference table. Check the unit definitions before you convert.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in kn; the result is in km/h.
Formula
Worked example
Convert 10 kn to km/h:
10 kn ≈ 18.52 km/h
Multiply your kn value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

Understanding knots
One knot equals one international nautical mile per hour, exactly 1.852 km/h. A knot already includes a time denominator, so it is not described as knots per hour.
Understanding kilometers per hour
Kilometers per hour measures distance per hour. Divide km/h by 3.6 to obtain m/s. An average trip speed includes stops if the total travel time includes them.
Precision and rounding
The calculator keeps decimal precision during the conversion. Displayed values use up to 10 significant digits; an approximation sign marks the reference results. Keep extra digits until your final measurement or purchase decision.
