To convert knots to km/h, use this simple formula:

Step-by-Step Speed Conversion Guide

1. Take your speed value in knots
2. Multiply it by 1.852 (the number of kilometers in one nautical mile)
3. Get your result in kilometers per hour

Common Knots to Km/h Conversions

Practical Applications

• Maritime Navigation: Ship speeds and sea current measurements
• Aviation: Aircraft airspeed and ground speed readings
• Weather Forecasting: Wind speed reports and storm warnings
• Sailing: Boat speed and wind conditions for sailors

What is a Knot?

A knot (kt) is a unit of speed equal to one nautical mile per hour (1.852 km/h). It is used in maritime and aviation navigation worldwide. The term originates from the practice of measuring a ship's speed by counting knots on a rope trailing behind the vessel.

Quick Conversion Tips

For quick approximations, remember: 1 knot ≈ 1.85 km/h, or roughly multiply knots by 2 and subtract 10%. For example, 10 knots ≈ 20 - 2 = 18 km/h (exact: 18.52 km/h).
