Knots to Kilometres per hour

1 knot = 1.852 kilometres per hour · 1 km/h = 0.53996 kn

1 knot = 1.852 kilometres per hour

How it’s calculated

km/h = kn × 1.852

  • Multiply the value in knots by 1.852.
  • To go back, divide by 1.852 (or multiply by 0.5399568035).
  • 1 kn = 1.852 km/h · 1 km/h = 0.5399568035 kn
Show worked solutionFactor, unit cancellation and rounding, step by step

  1. Find the conversion factor

    By definition 1 kn = 0.514444444444444 m/s and 1 km/h = 0.277777777777778 m/s, so 1 kn = 1.852 km/h. Source: NIST SP 811 / Handbook 44; BIPM SI Brochure (9th ed.) (SI prefixes and accepted units).

  2. Multiply by the factor written as a fraction

    Put kn in the denominator so it cancels, leaving km/h.

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.
