How many knots is a 50 km/h wind?
About 27 knots, the top of force 6, a "strong breeze", on the Beaufort scale. Marine and aviation forecasts give wind in knots even where weather apps use km/h.
How fast does an airliner cruise in knots?
A typical jet cruises at around 900 km/h, which is about 486 knots. Pilots work in knots throughout: take-off speeds, wind limits and cruise.
