Each human eye has a coverage of about 160°. The coverage overlaps giving about 90° of stereo vision. The foveal vision (high definition in the center) is less than 2°.
Between 24mm and 25mm, or about an inch.
2.34cm
it may be 120 degree for single eye and 175 dgree for both eyes
The first example: hair diameter
Earth is not a perfect sphere; it is slightly wider across the equator than it is from pole to pole, but that difference is less than a percent of Earth's average diameter, too small for the human eye to notice.
It varies widely. Some of the smallest eyes are around two to three miles wide. A normal size eye is about 15 to 30 miles wide. A very large eye can be over 60 miles wide. Generally the stronger the hurricane the smaller the eye.
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
Only half of the Human eye is showing.
Size of the eye doesn't change with age. The average size of a human eyeball is 2.4 cm.
it is 32cm in diameter
Between 24mm and 25mm, or about an inch.
The size of a human eye is the size of a golfball.But most of the eye is inside your head.The size of an eye of an average person will never change. If you want more detail or information go to http://wikipedia.com/eyes or you can read the book called "The human body".
The average diameter of human hair is 100 micrometres.
The average diameter is about 20-40 miles across. The calmness of the eye is deceptive. Once the eye passes the other side of the storm comes and so do the winds from the opposite direction.
With one hand, the average male human cannot hold and grasp a basketball from the top without it falling. The standard basketball is a little over 9 inches in diameter. Given that women will have smaller hands on average, the diameter that the average human can hold and prevent from falling, and this is complete conjecture, should be between 5-7 inches. But first, the average human hand size would have to be determined. With two hands, the largest diameter object the average human could hold would be significantly larger, dependent on the wingspan of the average human, the surface texture and the weight of the object, and the average height and strength of the average human .
The first example: hair diameter
approximately 100-150 on the upper eyelid for the average human

A human hair has an average diameter of 70 mikrometers and a capillary has an average diameter of 7 mikrometers, so that tells us that 1 hair takes about 10 capillaries in width.
