What This Site Is
KnotsConverter.com is a free, instant speed converter purpose-built for the knot — the unit of speed used by sailors, pilots, and meteorologists worldwide. You can convert knots to miles per hour, kilometers per hour, meters per second, feet per second, and Beaufort scale values. Every field updates in real time as you type, with no submit button required.
The converter is designed to load fast, work on any device, and get out of your way. There are no accounts to create, no data stored, and no cookies beyond what Google AdSense requires to serve contextual ads. The tool is free to use, and ad revenue keeps it running.
Why We Built It
Knots are a unit that most people encounter occasionally — during a hurricane forecast, while watching sailing coverage, during flight training, or while listening to a marine weather radio. In those moments, you want to quickly understand what a speed in knots feels like in everyday terms. A simple, accurate, fast-loading converter with no clutter is the right tool for that job.
The FAQ page on this site covers the most common questions: what a knot is, why mariners use it, how it relates to hurricane categories, and how various common speeds translate. We hope it serves as a useful reference beyond just the conversion math.
Accuracy & Methodology
All conversions use the internationally standardized nautical mile definition of exactly 1,852 meters. The conversion factors used are:
1 knot = 1.15078 MPH
1 knot = 1.852 km/h
1 knot = 0.514444 m/s
1 knot = 1.68781 ft/s
Beaufort scale assignments follow the World Meteorological Organization standard ranges. Results are rounded to two decimal places for readability. This tool is intended for general reference and informational use only — it is not designed or approved for navigation, aviation operations, or any safety-critical application.
