A light year is the distance traveled by light in one year. Multiply light years by 9,460,730,472,580,800 (approximately 9.5 trillion or 9.46 x 10**12) to get kilometers. Other values sometimes seen are the result of rounding errors in the speed of light, or in how to define a "year". Scientists tend to use "parsecs" rather than light-years; light years are used more in popular science publications.

∙ 15y agoIf speed of light is exactly 299,792,458 metres per second, and we know there are 31 556 926 seconds in a year, the distance light travels in a year is 31 556 926 x 299 792 458, so, the distance light actually travels is close to 9.4605284e +15 metres, about 1 trillion kilometers.

∙ 14y agoLight years have fewer calories than regular years, so it would be about 150 million. (Actually, light years are a distance unit and years are a time unit; you can't convert one to the other.)
Wiki User
∙ 14y agoLight travels at about 300,000 km per second.
There are 60 seconds in a minute, 60 minutes in an hour, 24 hours per day and 365.26 days in a year.
Just multiply all of those numbers together.

- A light year is a measure of distance.
- A year is a measure of time.
It's like asking how many miles in an hour.
------------------------------- WRONG, whoever put that analogy is stupid. You can convert light years into years.
Light year is the distance traveled by light in one year. Light travels at a speed of 186,282 miles per second and a year has 31,556,926 seconds. Thus light travels 5,878,499,817 miles in a year.

∙ 14y agoA light year is the distance light travels in one year and is a measure of distance or length. It equates to about 6 trillion miles.
Wiki User
∙ 12y agoSince a light-year has approximately 9.5 x 1012 kilometers, you must divide by that number.
Wiki User
∙ 14y agoLight takes 1 year to travel a distance of 1 light-year.
Light takes 230 million years to travel a distance of 230 million light-years.

How much would 280 mph converted in km be?
280 mph = 450.6 kph
When did the dinosaurs became extingt?
The last dinosaurs became extinct about 65 million years ago at the end of the Cretaceous period.
Is a pulsar a part of the solar system?
There isn't a pulsar in our Solar System. The closest known pulsar is 280 light years from us.
What is the normal carbon monoxide level in your body?
On earth carbon dioxide levels varied from 250 parts per million to 280 ppm over the past 800,000 years, per ice core samples. There is additional decent proxy evidence to indicate CO2 has not exceeded 280 ppm over the past 20 million years. Before the industrial revolution began in 1700, CO2 was at the 280 ppm maximum. We would expect without human activity CO2 would still be about 280 ppm, as the normal variation was roughly 5 parts per million over the course of a thousand years. Many scientists believe 350 parts per million might be earth's maximum sustainable level. We are now at 400 parts per million and at present rates will pass 500 parts per million before 2050, less than 40 years from now.
How much have the atmospheric carbon dioxide concentrations increased in recent years?
Over the last 150 years, CO2 concentrations have increased from around 300 ppm to around 400 ppm - mostly in the last 70 years or so. Current scientific thinking is that anything over 350 ppm is likely to have unwanted consequences.
What is 7.5 percent of 280 million?
7.5 percent of 280 million is 21 million.
Was a dinosaur the first Vertebrate?
The first vertebrate was Pikaia, which lived 510 million years ago, 280 million years BEFORE dinosaurs.
Is a helicoprion real?
Yes they are real. They were first on earth 280 million years ago and then went extinct 225 million years ago.
When did the Gorgonopsid live?
The late Permian, around 280 to 250 million years ago
How do you write 280 million?
280 million can also be written as 2.8*108 or 2.8E8.
How much would 280 mph converted in km be?
280 mph = 450.6 kph
What is 2.8 million in percentage?
It is 280 million%
What is 280 million times 1000?
280,000,000,000 or 280 billion
How many years did trilobites roam the earth?
Trilobites lived for 280 million years before they became extinct, from the Cambrian to the Permian.
