Contrary to popular belief, a light year is not the "longest unit". A parsec is. Or more specifically, a yottaparsec.
The length of a parsec is found by constructing a hypothetical right triangle where corner A is the sun and has an angle of 90 degrees, and corner B is the earth (the assumed distance between the two is one AU, the average distance between them, approximately equal to149,597,870.7 kilometres¹), and corner C has an angle of 1 second of arc (1/3600 of one degree). A parsec, then, is the distance between A and C, approximately equal to 3.26 light years².
The prefix "yotta" is the largest unit prefix of the SI denoting a factor 10^24 (a septillion, or 1000000000000000000000000)
A yottaparsec therefore is a septillion parsecs, or 3.26 septillion light years, and is a distance far, far longer than the universe itself.

What metric unit is the longest?
The metric unit of length is the metre. The only multiple in general use is the kilometre. There are as many other multiples as you would wish.
What is the longest and the shortest that the sum of two unit vectors can be?
The longest sum of two unit vectors occurs when they are aligned in the same direction, resulting in a maximum magnitude of 2. Conversely, the shortest sum occurs when the two unit vectors are directly opposite each other, yielding a minimum magnitude of 0. Thus, the sum can range from 0 to 2.
Which distance is the longest 23.23 or 23.54?
Assuming the numbers refer to the same unit of measurement, then whatever there are 23.54 of, there are going to be more of these than if there are only 23.23 of them.
What is the longest cell in the human body?
Cell is the structural and functional unit of life. And Nerve cell is the longest cell in the human body. So the motor and sensory cell that go to the feet are the longest cells in your body. They go from your back to the feet. The sensory cell go to the tip of great toe.

How do you find the longest wavelength?
By comparing the numbers. If the wavelengths are specified in different units (for example, meters and millimeters), you must convert them all to the same unit first.
