The size of 1MB is a measure of digital storage capacity, not a direct indicator of pixel dimensions. The number of pixels in 1MB would depend on the image resolution and color depth. For example, a 1MB image at a resolution of 1024x768 pixels and 24-bit color depth would contain approximately 2.36 million pixels (1024 x 768 x 3 bytes per pixel).
Megapixels is a measure of image resolution. Megabytes are measurements of file size. They actually have no direct relationship.
Megapixel (MP) count refers to the maximum resolution of the camera's sensor -- its ability to record detail. The number of images that can be recorded on a card of a given size is only indirectly related to the capacity of the card, which is measured in Kilobytes (KB) or Megabytes (MB), not MP. That will vary according to the image itself, and to the camera's settings.
For example: My Pentax K10D, with a 10.1 MP sensor and using a 4 GB card, will record approximately 821 images at the highest resolution (10 MP) and a "Fine" quality setting. The same camera, with the same sensor and same card, will record 10,000-plus images at the lowest resolution (2 MP) and the "Low" quality setting. Practically all cameras have this ability to change the resolution settings, and thus the sizes of the image files that are stored on the card.
So, you can see that it is only possible to answer your question in very general terms: The higher the capacity of the card, the more images you can store at whatever camera settings. And, as you can see above, even at the highest settings with a high MP count, you can take a lot of pictures!
One thing to think about: storage cards can and do fail. It is better to have two 1 GB cards than one 2 GB card, unless you plan to shoot a whole lot of video. That way if one fails, you can keep shooting and worry about retrieving the images off the other card later.
1 MB is a completely different measurement than pixels. Pixels measures area and length on a computer screen-basically dots. For example, the Answers.com logo is 290 pixels long and 54 pixels high.
Megabytes represents file sizes on a computer. These convert to bytes (B), kilobytes (KB), gigabytes (GB), and terabytes (TB). Usually you won't have to deal with file sizes, unless you're uploading a file. Generally the size limit for attaching files to an email is 10 megabytes.

1024KB (kilobytes) equal 1MB (megabyte) So 100KB is roughly 1/10 of a megabyte, or 0.1MB.
This looks like the dimension of a high definition computer screen - 1366 pixels wide and 768 pixels high. A pixels is defined as a picture element.
320 x 480 pixels typically would mean that the display of the technological device, (probably a television, computer monitor, or other visual device. etc.) would have 320 pixels on the shortest side of the screen and 480 pixels on the adjacent side. Thus the screen would have 153600 total pixels in the screen, but by writing the dimensions, the manufacturer can keep better track of the brands and not be faced with two different dimensions equalling the same number of total pixels.
1MB is equal to 1000KB.
Approximately.... 1MB = 200KB 2MB = 400KB
3.5 cm is equal to 132.283464567 Pixels
one megapixel is a million pixels, so 9.2 mega pixels would be 9.2 million pixels, or 9,200,000 pixels.
1 megabyte is equal to 1024 kilobytes.
1024kb=1mb
1 minute
5cm (at 720dpi) is 1.417 pixels.
1MB = 2 to the power of 20 bytes = 1024 x 1024 bytes
256Kbps is the same as 0.25Mbps, as 1MB is equal to 1024Kb... so 4 seconds would equate to 1Mb
1 MB (megabyte) is equal to 1024 KB (kilobytes).
It is 1000000/8 = 125000 bytes. supermanhelp.com
