About Speed Conversion
Speed measures how fast an object moves, calculated as distance traveled per unit of time. Different units are preferred in various contexts and regions.
Kilometers per hour (km/h) is used in most countries, while miles per hour (mph) is used in the US and UK. Knots are the standard unit for maritime and aviation speeds.
This converter makes it easy to switch between different speed units, useful for travel planning, sports analysis, or understanding weather reports.
