The video explains why speed on water and in the air is measured in knots. A knot represents one nautical mile per hour, about 1.15 miles per hour on land. This unit is preferred because nautical miles are based on the Earth’s latitude and longitude, making navigation easier for ships and aircraft. Using knots allows navigators to calculate distances accurately on charts and maintain coordination between sea and air travel. The practice dates back to when sailors used a rope with knots to measure speed, and it remains a standard in maritime and aviation today. https://www.accuweather.com/en/videos/why-do-we-measure-speed-on-the-water-and-in-the-air-as-knots/4b88cad3-1c26-4b25-b399-c4b4cee5f444
