Pilot Institute

Since it’s a ratio, it doesn’t matter if you measure speed in knots, miles per hour, or meters per second. At sea level on a standard day (15 °C or 59 °F), sound travels about 661 knots (approximately 761 mph or 1,225 km/h). When you reach around 36,000 feet (11,000 m) near the tropopause, the temperature stabilizes at around -56.5 °C.
