Speed of Sound Calculator vs iECHO GPA Usage & Stats
Speed of Sound Calculator is a physics/math calculator used to determine how the speed of sound in water or air changes with temperature.
Features:
- Instant calculation
- Results are copyable to other apps
- Formulas are included as references
- Supports up to 16 decimal places
- Supports various units for each input
The velocity of sound in air (ideal gas) can be expressed as:
c = √(γ * R * T / M)
where:
c - Speed of sound in an ideal gas
R - Molar gas constant, approximately 8.3145 J · mol⁻¹ · K⁻¹
γ - Adiabatic index, approximately 1.4 for air
T - Absolute temperature
M - Molar mass of the gas. For dry air, it's about 0.0289645 kg/mol
