How our Knots to Kilometers Per Hour unit converter works

To ensure maximum accuracy when converting Knots to Kilometers Per Hour, our calculator uses a scientific pivot method. Instead of relying on a potentially inaccurate direct conversion, the system first converts knot into the base unit of the International System (the meter per second), then recalculates the result into kmh. This approach drastically reduces rounding errors.

About this conversion

The knot (one nautical mile per hour) is the universal standard for maritime and aviation speeds, ignoring national borders.

When to use this conversion

Essential for boating on the Great Lakes, sailing on the St. Lawrence River, or tracking airplane cruising speeds.

Formula

Kilometers Per Hour (kmh) = Knots (knot) × 1.852

FAQ

How fast is 1 knot?

One knot is 1.852 km/h, or about 1.15 mph. It is based on the Earth's circumference.

Why don't boats use km/h?

Knots correspond to nautical miles, which are perfectly aligned with map coordinates (latitude/longitude) used in navigation.
