In one nanosecond (ns), light will travel 30.0 cm, about 1 ft.
The speed of light (in a vacuum*) =
186,000 miles per second, or
0.000186 miles per nanosecond, around 1 foot/ns.
*note: Light travels slower moving through matter.

∙ 14y agoIf the information given in the question is accepted as correct, then light travels one meter
in 330 nanoseconds.
But the decimal places/powers of ten in the question have slipped, and the given data-point
is inaccurate by a factor of 99.
The speed of light is 300,000 kilometers per second, or about 990,000 km in 3.3 seconds.
A more accurate time for a trip of one meter at light-speed is 3.3 nanoseconds.
Here's a cool rule of thumb for Americans: " 1 nanosecond per foot " is off by less than 2% .

∙ 14y ago"Kilometers per second" is a speed. "Light-year" is a distance. These two units measure different quantities and have different 'dimensions'. Neither one can be converted into the other one. A light-year is a distance of roughly 5,878,700,000,000 miles (9,460,890,000,000 kilometers).

∙ 14y agoThe speed of light in the standardized medium of free space is a physical constant defined as 299,792,458 metres per second. It is often denoted by the symbol c - originating from the Latin word celeritās (speed). The speed of light was officially included in the International System of Units on October 21, 1983, leaving the metre defined in terms of both c and the second. The speed of light in a material is the apparent speed that light travels in that material and may be very different than c. (In the simple view that matter is atoms in a matrix of free space, light moves at c in the space between atoms, but is constantly being absorbed and re-emitted, which delays it, and makes it appear to travel slower.)

∙ 11y agoA light year is a unit of distance, not a moving thing - it is the distance covered by light in a vacuum in one year.Light itself, however, travels at exactly 299,792,458m/s. This is often shortened to 3.00x108ms-1.

∙ 11y agoThe speed of light in vacuum is denoted by the letter c. It is a universal physical constant.
The value of c is 299,792,458 meters per second or 186,282 miles per second.
The value of c is 17,987,547,480 meters per minute or 11176920 miles per minute.
The value of c is1,079,252,800 kilometers per hour or 670,616,629,384 miles per hour.

Well: Light travels 186,000 miles per second...
(I answered this before but someone changed it so I lost my numbers, but here is the sequence):
186,000 mps:
*60 into hours
*24 into day
*5280 into feet
/ 3.28084 into meters...
With a result of... 431,046,683,166 meters per day.

How long does it take light to travel from one side of the galaxy to the other side?
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
How long would it take nasa to travel a light year?
There is currently no technology that would enable human astronauts, from NASA or from any other organization, to travel one light year. There are some theoretical proposals for ideas that might work, but nothing even on the horizon for now. we can travel in space ROUGHLY 30,000 mph...at that rate it would take us ROUGHLY 22,366 years to travel 1 light year
How long would it take to go one light year?
Depends on your speed. A light year is the distance light travels in a year. If you traveled slower it would take longer.Depends on the speed you are going.At the speed of light one year.See related question for details of a light yearJust like any other distance, it depends on the speed of travel.-- At the speed of light, radio, x-rays, etc., it takes 1 year.-- At 1 million miles per hour, it takes about 671 years.-- At 60 miles per hour, it takes about 11.2 million years.A light year is the distance that light will travel in one year in a vacuum. The speed of light is 186,000 miles per second. So, light will travel about 5.8 trillion miles in one year. Now, to answer the question. The answer depends on how fast you are traveling. If you were in a space ship travelling 99.9999% the speed of light, it would take you about a year to travel a light year. Now, there is currently no human-made space craft, that we know of, that can travel that fast. The space shuttle travels at about 17,500 miles per hour. In order for the space shuttle to travel one light year, it would take about 38,262 years.
How long would it take gamma rays from an exploding star to reach earth?
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
How long does it take to travel from one galixy to another?
At the speed of light, it takes millions of years. For example, the Andromeda galaxy, which is the closest galaxy to our Milky Way galaxy, is about 2.5 million light years away, that is, traveling at light speed it would take 2.5 million years to get there.
How long does it take for a lightyear to travel?
A lightyear is the distance that light can travel in one year.
How long does it take light to travel in 1 hour?
It takes light exactly one hour to travel in 1 hour.
How long does it take light travel one trillion miles?
Approximately two months.
How long does it take light to travel 186 miles?
That should be one-thousandth of a second.
How long does it take light to travel around the earth seven and half time is?
One second.
How long does it take light to travel from one side of the galaxy to the other side?
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
If you could travel at the speed of light how long would it take you to travel from one side of the milky way galaxy to the other?
Between 100,000 and 180000 years.
If you could travel at the speed of light how long would it take to travel from one side of the Milky Way galaxy to the other?
Between 100,000 and 180000 years.
How long does it take a light to travel one trillion miles?
Light travels at about 186,000 miles per second and so divide this into 1,000,000,000,000 which is about 5,376,344 seconds
How long would it take to travel only one light year?
What, walking, swimming? a long time. By definition one light year is how far LIGT travels in one year. That's 5.8 trillion miles, or 5,800,000,000,000!
How long by car would it take to travel on US route 66 in one second of a light year?
The question can't be answered. At least not in its present incomprehensible form. -- "light year" is a distance -- "one second" of that distance is meaningless -- "how long ... in one second" seems even less so If you mean, how long would it take a to travel one light second by car, then the answer would be something like this: One light second equals 186,000 miles. Assuming that the car travels at the speed limit of 70 miles/hour, it would take 186,000/70 = 2657 hours = 110 days 17 hours to travel one light second.
How long does it take for light to travel through space?
It takes one second for every 299,792 km (186,282 miles) it has to cover.
