Like dog 1 dog year= 7 years for us. But this question I ask is, how many regular years are in one lightyear.

A light year is a measure of distance and time.
A light year represents the distance traveled by light in one year. Light travels at approximately 300000 kilometers per second (approximately 186000 miles per second); so, a light year represents the distance of approximately 9.5 trillion kilometers (approximately 5.9 trillion miles)!

a number from 0 to infinity,
A lightyear is a measure of distance (distance travelled by light in 1 year) not a measure of time.
1 LY = 9.461×10^12 km

A lightyear is a measure of distance, not time. How far a light travels in one year is a lightyear.
For the record, it's 5,865,696,000,000 miles.

A lightyear is a measure of distance, specifically the distance light will travel in a year. It's not a measure of time.

No, it is not in that sense though I can see where you could easily think that. Dog year light year...sounds like a pattern to me! Anyway, it is the distance light travels in one year. See, the universe is so incredibly vast that they needed a form of measurement big enough to chart distances between things that didn't always have exponential equations. For example, 5,880,000,000,000 miles or 5.88 trillion miles is the amount of miles light actually travels in one year. It is also written 5.88 x 10 to the 12th power but you can see how huge that is and it can be quite intimidating and confusing when getting larger distances like 1,210 lightyears. Try converting that to miles. You could but who would want to??? Anyway, hope I helped.

Well, If 1 human year = 7 dog years, we are trying to say that relative to a human, dogs age faster and do not live as long. Since Photons do not experience the passage of time at all due to relativistic time dilation, then 1 light year would equal 0 human years.
I think you are confused however, since the light year is a measurement of distance, not time. It is the distance that light will travel in one sidereal earth year. kind of like miles per hour but bigger.

All this is true distance and all that. Bottom line one light year is equal to one regular year. A year is measured in days and therefore hours seconds etc. Let's say that you are walking one meter per second, light in that same second will cover a distance of 300000 km> so one light year is the distance that light will cover in one standard earth year. Please keep in mind that the units used for time measurements, distances etc are conventions invented by man and not absolute numbers.

A lightyear is a unit of distance, not time. It refers to the distance that light will travel in one year. It is 9.4x10^17 cm.

May be if we divided the distance that light travels in one year over the diaiameter of earth "puting in mind that one diameter = one Earth day" then divide the result over 365 , we can get a roughly number of how many years in one light year. Just saying!

A light year is not a length of time. It is a measure of distance. A light year is the distance light travels in a vacuum in one earth year.
