Speed of Sound Calculator
Sound Speed & Acoustic Calc
$2.99 · Designed for iPad. Not verified for macOS.
Calculate the speed of sound through air, water, and solids — instantly and accurately.
Speed of Sound Calc. is a precision physics calculator designed for students, engineers, scientists, and audio professionals. Whether you're studying acoustics in class, designing sonar systems, or solving physics homework, this app gives you reliable results with a clean, intuitive interface.
— SPEED OF SOUND CALCULATOR —
Calculate how fast sound travels through different media:
• Air — uses the standard temperature-dependent formula (v = 331 + 0.6 × T). Adjust temperature with a slider or type an exact value. Supports Celsius, Fahrenheit, and Kelvin.
• Water — includes both freshwater (1,482 m/s) and seawater (1,531 m/s) reference values.
• Solids — built-in constants for steel (5,960 m/s), wood (3,850 m/s), and aluminum (6,420 m/s).
• Custom — enter any speed value for your own medium or material.
— TIME OF FLIGHT CALCULATOR —
Enter a distance and the app calculates how long it takes sound to travel that distance through your selected medium. Perfect for estimating echo delays, sonar timing, or ultrasonic sensor calibration.
Formula: time = distance ÷ speed
— DISTANCE CALCULATOR —
Enter a time duration and calculate how far sound travels. Useful for lightning-to-thunder distance estimation, range finding, and acoustic measurement.
Formula: distance = speed × time
— UNIT CONVERSION —
Switch between units on the fly:
• Speed: m/s, km/h, ft/s, mph, knots
• Distance: m, km, ft, miles
• Time: seconds, milliseconds, minutes
• Temperature: °C, °F, K
All results update live as you change inputs or units.
— BUILT FOR PRODUCTIVITY —
• Tap any result to copy it to your clipboard
• Save calculations to a local history log
• Review and manage past calculations anytime
• Works completely offline — no internet required
— DESIGNED FOR ALL DEVICES —
Optimized for both iPhone and iPad with a responsive layout. Supports Dark Mode for comfortable use in any environment. Clean, distraction-free interface follows Apple Human Interface Guidelines.
— PHYSICS REFERENCE —
Access a built-in reference page with all formulas, speed constants, and important notes about the approximations used — so you always understand the science behind the numbers.
