How many pixels are typically represented in one megapixel?

A megapixel is a unit of measurement that is commonly used in the context of digital imaging. It refers to one million pixels. This term is often used to describe the resolution of cameras and images, indicating how many individual dots of color make up the image. Higher megapixel counts generally allow for more detail in the photos because more pixels mean more data is captured.

In this instance, the correct answer signifies that one megapixel is equal to one million pixels, providing a clear understanding of digital image sizes and their potential clarity. The other numbers presented do not accurately reflect the definition associated with a megapixel.
