At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.92 s or one mile in 4.69 s. It depends strongly on temperature as well as the medium …

Speed of Sound at a known temperature and density of air. Speed of Sound vs Density of Air. Effect of temperature on properties of air. Given normal atmospheric conditions, the temperature, and thus …

Dec 28, 2025 · The speed of sound is a fundamental concept in physics, representing the rate at which sound waves propagate through a given medium, such as air, water, or solids. In dry air at 20°C …

May 21, 2024 · What is the Speed of Sound? The speed of sound varies depending on altitude, temperature and the medium through which it travels. For example, at sea level in a standard …

The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at 20 °C is equal to 343 meters per second, [1] or roughly 767 miles per hour.

Definition: This calculator determines the speed of sound in both meters per second (m/s) and miles per hour (mph) based on air temperature. Purpose: It helps in physics, engineering, and meteorology to …

This page explains the speed of sound, which varies by medium and is primarily influenced by temperature, with specific formulas for gases and considerations for solids and fluids.

The speed of sound, therefore, relates to the speed at which the pressure wave travels as each particle hits its neighbor. Because air is not particularly dense, sound travels relatively slowly as compared …

Mar 1, 2026 · speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is …

The speed of sound is approximately 767 miles per hour (mph) at sea level and at a temperature of 20 degrees Celsius (68 degrees Fahrenheit). However, this speed can vary depending on factors such …
