Pourquoi les BATEAUX et les AVIONS utilisent-ils des “NŒUDS” et non des KM/H ?

Why do boats and planes use knots instead of km/h? The answer lies in the fascinating history of navigation, when sailors measured speed with a rope and… real knots! In this video, we explore the origin of the knot, why this unit has remained essential at sea and in the air, and how it provides a level of precision that km/h simply can't match. You'll discover: • Why one knot = 1 nautical mile per hour • The difference between km/h, knots, and nautical miles • Why pilots and ship captains can't do without knots • How this unit became an international standard in modern aviation and navigation If you finally want to understand why the maritime and aviation worlds don't use km/h, you've come to the right place. 👍 Like the video if you learned something! 🔔 Subscribe to discover more everyday science and technology stories! 💬 Tell me in the comments: did you know the origin of knots? #knots #speed #boat #plane #navigation #aviation #nauticalmile #kmh #curiosities #science #history #explanation #transport #maritime #piloting #nauticalmiles #speedinknots #whyknots
