How fast is the Speed of Sound?
The speed of sound (Mach 1) is approximately <strong>1,235 km/h (767 mph)</strong> in dry air at 20°C. Supersonic jets fly faster than this, creating a sonic boom.

Speed Visualization: How Fast is Fast?
Speed is an abstract concept. We simply know a car is faster than a bicycle, but by how much? Is a cheetah really that fast compared to a race car? Numbers alone often fail to convey the true scale of velocity.
This tool lets you compare everyday speeds (walking, cycling) with mechanical marvels (supercars, bullet trains) and even cosmic phenomena (rockets, speed of light). Visualize the massive difference in motion relative to your own speed.
Frequently Asked Questions
Can anything go faster than Light?
According to Einstein's theory of relativity, <strong>nothing can travel faster than light</strong> in a vacuum (approx. 300,000 km/s). It is the cosmic speed limit of the universe.
What is the fastest man-made object?
The <strong>Parker Solar Probe</strong> is the fastest object ever built by humans. It is expected to reach speeds of over <strong>690,000 km/h (430,000 mph)</strong> as it orbits closer to the Sun.
