Speed of Sound Calculator
Calculate the speed of sound in dry air at different temperatures. Shows results in m/s, km/h, mph, knots, and ft/s with the formula used.
How to Use Speed of Sound Calculator
The Speed of Sound Calculator determines the speed of sound in dry air at any given temperature. Enter the temperature in Celsius, Fahrenheit, or Kelvin and get the speed of sound in multiple units: meters per second, kilometers per hour, miles per hour, knots, and feet per second. Uses the formula c = 331.3 × √(1 + T/273.15) for dry air. Essential for aviation professionals calculating Mach numbers, acoustics engineers, physics students, and anyone working with sound propagation. The result represents Mach 1 at the given temperature.
Step-by-Step Instructions
- Enter the air temperature
- Select the temperature unit (°C, °F, or K)
- Click Calculate
- View the speed of sound in multiple units
