While it is truly an unconventional (and not very useful) unit, yes it is. Speed (and velocity) are shown as a ratio of elapsed distance to time. Therefore, since a light-year is a measure of distance and a century is a unit of time, this is a unit of speed (or it could be used to measure velocity).

How many g's is the speed of light?
speed of light is constant velocity and does not accelerate so there is no g force
How does these two quantities determine the speed of light?
The distance in meters covered by light in one second is considered to determine the speed of light. Speed of light is 3*108m/s. The unit of speed of light is meters per second.
What is the speed of light in hurtz?
Hz (hertz) is a unit of frequency, not of speed.
What is the unit that astronomers most often use to express the wavelength of light?
Speed of light
Are speed of light and the frequency of light the same?
No, the speed of light is the speed at which a photon (the particles that make light) travels. While frequency is the number of times per a unit of time a wave cycles from peak to peak. Different frequencies produce different colours.
How many g's is the speed of light?
speed of light is constant velocity and does not accelerate so there is no g force
Is century a metric unit?
No. Century is a measurement of time. A century is 100 years

Which mectric unit would be used for the speed of light?
lightyear.
What is the unit that astronomers most often use to express the wavelength of light?
Speed of light
Would it take light years to finish homework?
A light-year is a unit of distance, not a unit of time.
How long it would take to go 4900 light years?
At the speed of light, it would take 16.6 years. Since it takes 4,700 years instead, your speed must be(16.6/4700) times the speed of light.(186,282) x (16.6/4700) = 657.9 miles per second = 2,368,600 miles/hour (rounded(300,000) x (16.6/4700) = 1,059.6 km/sec = 3,814,500 km/hour (rounded)
How many light years is one of owr years?
It doesn't make sense to convert that. A light-year is a unit of distance, not a unit of time. A light-year is the distancelight travels in a year.
Is the speed of light is a basic unit or a derived unit?
The speed of light, abbreviated as "c", is a fundamental constant. It is 299,792,458 meters per second, and the length of the meter is DEFINED AS being 1/299,792,458th of the distance that light travels in one second. So it is a "basic unit". We generally use 300,000 km/second or 186,000 miles per second as "close enough" approximations of the speed of light.
How old is mira the star in light years?
"Light-year" is NOT a unit of time. It is a unit of length or distance - the distance light travels in a year.
How can the universe be 156 billion years in diameter if it is only 14 billion light years old?
The diameter must be expressed in a unit of distance/length - for example in light-years - NOT in years. The answer is that the distant parts of the Universe are going away from us, faster than the speed of light. Inside its own local space, nothing can move faster than the speed of light. But in the case of the expansion of the Universe, you might say that space itself is expanding. This makes it possible for objects to move away from us faster than light.
