How much shorter would you have to make a meter in order to round the speed of light up to 300000 kilometers per second?

The speed of light is 299792.458 km/s.
To round it up to 300000 km/s the meter would have to decrease in length to
299792.458 ÷ 300000 x 1 m = 0.9993081933... m
that is a little under 0.7 mm shorter than it currently is.
(or a little under 692 μm shorter than it currently is.)

What travels at 300000 kilometers per second in a vacuum?
The closest is the speed of light at 299,792,458 kilometers per second.
What is 300000 kilometers per second?
That is the speed of light. (or any other wave in the electro-magnetic spectrum).
How fast can light waves travel in a second if it's moving through a vacuum?
Approximately 186000 miles/second or 300000 kilometers/second
If you plot the distance that light travels on the graph and it travels at a speed of 300000 kilometers per second what is the slope of the graph?
If you are plotting distance versus time it is a straight line with slope 300000
If Light travels in a straight line at a constant speed of 300000 kilometers per second What is the light's acceleration?
Trick question. A "constant speed" automatically means zero acceleration -- there is no change in speed.
How fast can light travel in one year?
300000 km/second
Light travels about 300000 km in a single second through air?
No. In a vacuum.
What travels at the speed of 300000 kilometres per second?
That is approximately the speed of light (c). In metric units it is exactly 299792458 meters per second (299792.458 kilometers per second). Even electrons in atoms travel at approximately the same speed (but always less than speed of light)
How fast is light in km?
300,000 kilometers/second.300,000 kilometers/second.300,000 kilometers/second.300,000 kilometers/second.
How many kilometers is 8 light years?
300000 x 60 x 60 x 24 x 365 x 8 = 75686400000000 kilometers
Why is the speed of the light is 300000 km per second?
299 792 458 m / s
How much time you need for 15km with the speed of light?
Since the speed of light is approximately 299,792 kilometers per second, it would take only around 0.00005 seconds to travel a distance of 15 kilometers at that speed.
