About the knot and the kilometer per hour

The knot

The knot (kn) is one nautical mile per hour, or exactly 1852/3600 ≈ 0.5144 m/s. It is the standard speed unit in maritime and aviation use because it relates directly to latitude — one knot covers one minute of arc per hour. The name comes from the historical practice of measuring ship speed by counting knots passed on a line trailing behind the vessel.

The kilometer per hour

The kilometer per hour (km/h) is the standard speed unit on road signs almost everywhere except the United States and the United Kingdom. To convert to meters per second, divide by 3.6 (since 1 km = 1000 m and 1 h = 3600 s).
