Speed of Sound Calculator
Estimate sound speed by medium and temperature, then calculate travel time, echo return time and wavelength.
Hit Calculate to see the speed range
Calculate to see echo timing
Metrics appear after calculation
Your explanation appears here
Warmer air generally increases sound speed because molecules transfer pressure changes faster.

Adjust temperature and distance to preview travel and echo timing.
Calculate your baseline first
For dry air this tool uses v = 331.3 × √((T + 273.15) / 273.15), where T is temperature in Celsius. Other media use typical reference speeds.
Sound travels through mechanical vibrations. Liquids and solids are usually much stiffer than gases, so pressure waves propagate faster despite differences in density.
No. Real sound speed depends on humidity, pressure, salinity, material grade and temperature distribution. Use certified data and instrumentation for engineering or safety-critical acoustics.
