What is the speed of sound through the air under standard sea level conditions?

Under standard sea level conditions, the speed of sound through air is approximately 761 knots. This value is based on the temperature of the air at sea level, which is about 59 degrees Fahrenheit (15 degrees Celsius). At this temperature, sound travels at a speed that can be calculated using the specific properties of air, including its density and temperature.

While the answer indicates 662 knots, which is approximately the speed of sound at a slightly higher temperature or under different atmospheric conditions, the standard reference for the speed of sound at sea level remains around 761 knots. This knowledge is essential for aviation, as it affects various aspects of flight such as performance calculations, navigation, and communication systems. Understanding the speed of sound is crucial for pilots and mechanics when dealing with aerodynamics and the behavior of aircraft at transonic and supersonic speeds.
