unit for measuring length
You can invent any number of nonstandard units, but none of them is "best". It is best to use standard units, that is, the meter.

What meter is A meter is a kind of length observed in the metric system. A meter is best known as 100 centimeters, but there are a lot more ways to convert a meter. It is part of 2 school subjects, which are measurements and math. Since measurment is a part of math, you can decide which one you prefer. That's your answer to the question "What is meter".Another AnswerIt depends where you live. If you live in the United States, then a meter can be a measuring device or the SI base unit for length. Practically everywhere else, a meter is a measuring device and a metre is the SI bas unit for length (different spellings).
Work(distance)
Depends on the use of the scope - target, hunting, etc. Will also depend on the caliber, and whether firearm or air rifle or handgun. 120 feet (40 yards) is not a great distance (I predator hunt at 500-600 yards) so a very high magnification scope is not needed- 2.5- 4x should be adequate unless you are shooting TINY targets.
the kilometer measurement is best suited
"Best" depends on what you want to use it for. Hunting squirrels you will need a different scope than you would use for 100 meter benchrest shooting. Like most things, you will get what you pay for. The higher dollar scope is likely to be brighter, not fog up, hold a zero, and be more durable.
100 meters.
If you spend most all of your hunting time in thick woods & brushy areas - I would consider a fixed power scope ( 4x should be good ). I personally use a variable power scope ( 3x9 ). This way I can cover both woods & more open areas. Since you will not be shooting over about 100 yards, something with a wide field and not too much magnification is best.
A meter is a standard unit of metric measurement for distance. To be perfectly frank, a meter stick is probably the best thing to reference when searching for something that is precisely one meter long. One meter translates into 3.2808399 feet.
It depends on the model you're using. All the models don't come with the same range. I'm currently using the Ncstarpistol scope that comes with a variable power magnification to provide ability to see shorter to longer distant target. The Ncstar 2-7x32 also has a best long eye relief scope too!
A telescope with low to medium magnification and a wide field of view would be best for observing the moon. This allows you to see the details on the moon's surface while also capturing the surrounding lunar landscape.
The meter. If the distance is large, you may want to use kilometers instead; if the distance is small, millimeters or microns (= micrometers).
AS is visited various site i found IT OR CS engineering has the best scope
bscs is best as it has much scope in india as well as abroad too.
Depends on what you are shooting. Targets, varmints, or big game. for deer, I use a 3x9 variable. An expreme high power scope may limit the field of view to a degree that I can't FIND the deer in the scope. Long range target, a 12 power scope. Varmints (woodchuck) I use a 6x24 power. More powerful scopes tend to have a smaller field of view, and be less bright.
