Conversion number between **speed of light** [c] and
**speed of sound** [s] is **875041.63854798**.
This means, that speed of light is bigger unit than speed of sound.

Switch to reverse conversion:

from **speed of sound** to **speed of light** conversion

[c] |

Result in **speed of sound**

- 1 speed of light = `(299792458) / (342.603648550333)` =
**875041.63854798**speed of sound - 1 speed of sound = `(342.603648550333) / (299792458)` =
**1.1428027604028 × 10**speed of light^{-6} - ? speed of light × `(299792458 ("m/s"/"speed of light")) / (342.603648550333 ("m/s"/"speed of sound"))` =
**?**speed of sound

If conversion between **speed of light to metre-per-second** and **metre-per-second to speed of sound** is exactly definied, high precision conversion from speed of light to speed of sound is enabled.

Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!

Convert **Speed of light to other unit:**

### speed of light

Definition of speed of light unit: ≡ 299 792 458 m/s. Light velocity (in vacuum) is one of the basic physical constants. Sign c (Latin celeritas = speed). Its value is exactly: 299792458 m/s. Example: electromagnetic waves propagation speed 1 c.

Convert **Speed of sound to other unit:**

### speed of sound

Definition of speed of sound unit: ≡ (1.4 x 286 x (20+273.15) )^{-2}. Speed of sound in the air. But this speed varies between 295-340 m/s depending on the air temperature and pressure. From the NASA formula I calculated the speed on sea level at 20°C.
