The first 3.5 inch diskette was 720KB, with 1440 sectors of 512 bytes for 737,280 bytes. The next one was Double Density labeled 1.44MB diskette with 2880 sectors of 512 bytes for 1,474,560 bytes. Divide by 1000 twice it should be 1.475MB. Divide by 1024 twice it should be 1.406MB. Only by dividing by 1024 once and 1000 once do you come up with 1.440MB. Kind of like mixing metaphors.
