The Beaufort scale is a time honored way of describing wind strength by its observable effects, from smoke rising straight up in a dead calm to widespread destruction in a hurricane. Devised in 1805 for the Royal Navy and still used today, it turns a wind speed into a single force number from zero to twelve, each with a descriptive name and characteristic signs on land and at sea. This reference tool lets you enter a wind speed in your preferred units and instantly maps it to the correct Beaufort force, showing the name, the equivalent speed range, and what you would typically observe. It is handy for sailors, kite and drone flyers, forecasters and writers who want the right term for a given wind. You can also browse the full table of all thirteen force levels. Everything runs locally in your browser for immediate, private lookups.
