What to enter
| Input | Meaning and units |
|---|---|
| Air temperature (°C) | Enter air temperature in °C; use the same basis as the other measurements. |
Understanding your result
Read Approximate sound speed (m/s) in the units and model stated on this page. The formula speed=331*sqrt((temperature+273.15)/273.15) defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
