Megapixels and megabytes are not directly related. Pixels are used to describe the resolution of an image, whereas bytes are used to describe a measure of data. mega- is a prefix used to describe how much of them there are (1 million).
If, for instance, a 1 megapixel image is stored with 24-bit color (8 bits for red, 8 bits for green, and 8 bits for blue), the total amount of memory required to store it would be 3 megabytes (24 megabits / 8 bits per byte). On a disk, an image is stored with less space than this, though, due to data compression. A diagram or other line art can be stored with fewer bytes using "lossless compression", like a .zip file or .png file, while a photographic image is usually reduced in size through "lossy compression" which throws away some data that we don't really notice with our eyes.

How many photos can 19 MB hold at 12 megapixels?
= How many photos can 19 MB hold at 12 megapixels? =
How many megabytes does and average photo use?
usually around 1MB, but it depends on the megapixels of the picture. Mine is 15 megapixels camera
What is the formula to calculate the number of 7.1 megapixel photos that can be stored in 512 MB?
We have to remember that: 1) 1 PIXEL=3 BYTES=24 BITS (FROM A COLOUR PERSPECTIVE, SINCE THE NUMBER OF BITS HAVE TO BE MULTIPLIED TIMES 3. THAT IS, 8 TIMES 3 EQUALS 24) 2) 1 MEGAPIXEL=3 MEGABYTES (APROXIMATELY) 3) 170.6 MEGAPIXELS= 512 MEGABYTES 4) THE ANSWER IS... APROXIMATELY 25 IMAGES OF 7 MEGAPIXELS EACH WILL FIT INTO A 512 MEGABYTES MEMORY CARD.
How many color photos can a 2gb memory card hold?
The number of color pictures that can be stored on a 2GB memory card will vary depending on the megapixels and file size of the photo. It can vary between 1430 photos when the photos are 4 MP and have a file size of 1.2 MB to 260 photos when the photos are 22 MP and have a file size of 6.6 MB.
How many pictures on 32GB memory card in 20 mega pixel digital camera?
No 28 mb but it might help http://www.crucial.com/support/how_many_pictures.aspx
Is a gigabit bigger or a megabit?
A gigabit is 1000 times the size of a megabit, I believe. If this is the same as bytes (I believe the values are 1/8 of bytes), meaning 1000 (1024, really) megabytes = 1 gigabyte, then 1000 (1024, I assume) megabits = 1 gigabit. Either way, giga is always greater than mega, whatever the suffix is.
How many megapixels your eyes?
576 megapixels
How many megabytes does a chest x ray require?
depends on imaging system. they range from 5 to 10 megapixels each. each megapixel requires 1.5 megabytes of storage because of 12 bit grayscale. So... best equipment produces 10 megapixel image requiring 15 megabytes of information to be stored. The images are stored in jpeg2000 format which cuts the size in half using nonlossy compression. So summary it takes up to 7.5 megabytes of space on the hospital hard drive to store one xray.
How many pixels are in the human eye?
576 Megapixels
How many megapixel in a MB?
Mega pixels and Mega Bytes (mb) measure two different things. Megapixels measure resolution and Mega bytes file/capacity size. Whilst there is a correlation (a larger resolution has more data to hold, so the picture has a greater file size) there are many different picture file formats (hence the different extentions, JPG, PNG, etc.) each of which compress the data differently. It is therefore impossible to give a direct conversion.
How many megapixels are in the HTC evo?
