How do you calculate compression ratio?
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
How do you calculate the compression ratio produced by the JPEG encoding?
You cannot calculate it, since it depends on some varying factors like the image content and some other JPEG parameters like optimization or progressive. You can use a program, e.g. AZImage - see links -, that allows you to fine set the compression parameters to get an idea about the resulting size.
How is magnification calculate?
It can be measured as the ratio between two points in the image compared to the same two points in the pre-image.

What is the highest compression ratio?
Compression ratio simply means the difference in size of the original vs compressed unit. Compression ratio is a commonly used term for internal combustion engine piston/cylinder compression and file compression. Ratios differ depending on the type of engine or the type of file being compressed. In file compression, 7zip has the highest compression ratio.
