Speed of Sound Calculator

Find the speed of sound in air at a temperature.

Speed of sound 343.42

Speed of sound 768.21

Formula: v = 331.3 + 0.606 × T(°C)

Step-by-step with your numbers:

1. Values used:

2. Air temperature = 20 °C

4. Speed of sound = 343.42

5. Speed of sound = 768.21

Did we solve your problem today?

Sound travels faster in warmer air.

The math behind it

v ≈ 331.3 + 0.606 × temperature (°C) m/s in dry air.

20 °C → 343.4 m/s.

In water?

Much faster — about 1,480 m/s.
