buying a camera

[Miss winning]

How many pixels make up one megapixel? is this something i should know before i buy new camera and is so what is the answe, thanks

I think 1 megabyte is 1024 bytes, therefore 1 megapixel is 1024 pixels. However, digital cameras come in denominations of millions of megapixels.
I hope this helps.
