What does a floppy disk (5.25", DD) represent?

It is a 5.25-inch double-density floppy disk used mainly in the late 1970s and 1980s as a portable magnetic storage medium with about 360 kilobytes of usable space.

What is meant by Zip 250 in data storage?

Zip 250 indicates a legacy removable disk format with a nominal storage capacity of about 250 megabytes and is a product-specific label rather than a standardized data unit.

Why are conversion results only approximate?

Because Zip 250 is a non-standardized unit and actual storage capacities can vary due to formatting and file system overhead on both floppy and Zip disks.
