It is 300000000 metres per second, approx.
The speed of light cannot be measured IN A WAY. However it travels at 1,079,252,848.8 miles per hour or 299,792,458 meters per second. It cannot be measured however the numbers I showed is one way. Light cannot have a specified measurement, unless the light source is big or small etc...
Since length is measured in meters, and time in seconds, it follows that speed is measured in meters/second.
The SI unit for tangential speed is meters per second (m/s).
Hz (hertz) is a unit of frequency, not of speed.
The exact speed of light in a vacuum is approximately 299,792 kilometers per second or about 186,282 miles per second.
This is commonly expressed in meters/second, kilometers/second, or miles/second. To use SI units, use meters/second.

It doesn't matter where YOU are when you make the measurement.But when the LIGHT is in vacuum, its speed is 299,792,458 meters per second.
299,792,458 is the speed of light in a vacuum, measured in meters per second. It is a fundamental constant in physics and plays a crucial role in determining the structure of the universe and the behavior of light in various mediums.
Since length is measured in meters, and time in seconds, it follows that speed is measured in meters/second.
Velocity(speed).
The speed of light in a vacuum is approximately 299,792,458 meters per second.
Velocity is measured in meters/second in the S.I. system.
The SI unit for tangential speed is meters per second (m/s).
The frequency, or number of cycles per second is measured, then divide the speed of light in meters per second (299,792,458) by frequency to get wavelength in meters. Example: 7 Mhz = 7,000,000 hz 299792458 / 7000000 = 42.8 meters.
The speed of an object falling from a great height is measured in meters per second per second until it reaches terminal velocity (maximum downward speed).
It's calculated, not measured. It's the speed of light ... 299,792,458 meters per second ... multiplied by the number of seconds in a standard year.
