The speed of light is a constant value of about 299,792,458 meters per second, which is equivalent to about 299,792,458,000 hertz (Hz).
The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s), which is equivalent to about 186,282 miles per second (mi/s).
The speed of sound in air is approximately 343 meters per second, which is equivalent to 1235 kilometers per hour. The speed of light in a vacuum is about 299,792 kilometers per second.
The speed of light in vacuum is 299,792,458 m/s usually rounded to 300,000 km/sec.The speed of sound at sea level is 343 m/s.The difference is 299,792,115 m/s.That's 99.999 886 % of the speed of light, and may also be rounded to 300,000 km/sec.
The speed of light is about 300,000 kilometers per second (3 x 108 meters per second); the distance light travels in a year is called a light-year. It is equivalent to about 9.5 x 1015 meters.
Energy is directly proportional to the square of the speed of light (in vacuum), where the constant of proportionality is the mass equivalent of the energy.
Energy has an equivalent mass; you can divide energy (in Joule) by the square of the speed of light (the square of 300,000,000 m/sec). The result is in kilograms.Energy has an equivalent mass; you can divide energy (in Joule) by the square of the speed of light (the square of 300,000,000 m/sec).

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s), which is equivalent to about 186,282 miles per second (mi/s).
That is approximately equivalent to 1 light-year. That is to say, if travelling at the speed of light - the highest possible speed in the Universe - it will take a year to get there.
1.5 million light-years is equivalent to the distance that light travels in 1.5 million years.
The speed of sound in air is approximately 343 meters per second, which is equivalent to 1235 kilometers per hour. The speed of light in a vacuum is about 299,792 kilometers per second.

Energy equals mass times the speed of light squared. Energy and mass are equivalent.
The escape velocity from a black hole is equal to or greater than the speed of light. This means that nothing, not even light, can escape from a black hole once it has crossed its event horizon.
