Bandwidth conversion tables
Common network media type bandwidth figured converted to file transfer times per minute and second
Notes:
- Network speeds are universally measured using base10 (decimal) numbering system. This means that a kilobit is equal to 1000 bits.
- File sizes on computers are almost always measured using base2 (binary) numbering system. This means that a kilobit is equal to 1024 bits.
- Just to confuse things further, storage capacity (of hard drives etc) is measured using base10 (decimal) numbering systen.
- For the purpose of this table, both base10 (kilo, mega, giga, etc) and base2 (kibi, mebi, gibi, etc) are provided.
- These figures do not include any protocol overhead such as tcp/ip and ethernet framing, start and stop bits etc. Therefore real world figures reported by your favourite file transfer program will be a few percent lower.
