Convert Knots to Kilometers per Hour

The Conversion Formula

To convert knots to kilometers per hour, multiply the value by the conversion factor: 1 kn = 1.852 km/h. For a worked example, suppose you need to convert 25 kn to kilometers per hour: 25 × 1.852 = 46.2999 km/h. To convert in the opposite direction, divide by 1.852, or equivalently multiply by 0.539958.

About knots

The knot is a unit with a literal history: sailors used to measure speed by throwing a log overboard attached to a rope with knots tied at specific intervals. They counted the knots that slipped through their hands in a set time. One knot equals one nautical mile per hour. It remains the global standard for maritime and aviation operations. knots are commonly used in Ship speed, Aircraft airspeed, Cruise missile velocity, and Wind speed (Marine), Naval operations.

A large cruise ship travels at about 20-25 knots.

About kilometers per hour

Kilometers per hour (km/h) is the standard unit for speed limits and car speedometers in almost every country except the US and UK. It gained dominance as the metric system spread in the 20th century. Even in the UK, which uses mph on signs, car speedometers must also show km/h. kilometers per hour are commonly used in Speed limits (Global), Car speedometers, High-speed trains, and Bicycle computers, Weather reports (some countries).

Highway speed limits are often 100-130 km/h.

When Would You Convert knots to kilometers per hour?

Converting between knots and kilometers per hour is one of the most common speed conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 kn = 1.852 km/h) memorized or bookmarked can save time in professional and everyday contexts alike.
