Can I use this tool to physically read data from a 5.25" floppy disk on a 3.5" drive?

No, this tool provides numeric conversions of storage units only; physical reading requires appropriate hardware.

Why does the conversion not equal a whole number?

Because the storage capacities differ between the two floppy disk formats, the conversion uses a ratio reflecting nominal sizes.

Is this conversion accurate for all data transfer needs between these disks?

This conversion describes nominal capacity ratios and does not account for formatting or file system differences which affect usable storage.

Preserving legacy software installations and boot media for historical computing.

Tips & Best Practices

Ensure compatibility of floppy drives when transferring data between disk formats.
Use conversion as a guide alongside suitable hardware or software tools for physical data transfer.
Consider differences in file system formatting that may affect actual storage usability.

Limitations

Conversion is based on nominal storage sizes and does not include formatting or file system overhead.
Physical floppy drives for each disk type are needed; direct interchangeability is not possible.
Actual data transfer requires compatible hardware or conversion software beyond numeric conversion.
