`T = f( S , "Ethernet")`

Enter a value for all fields

The Data Transfer Time calculator computes the amount of time needed to transfer an amount of data (S) via one of many transfer media (e.g. Ethernet).

INSTRUCTIONS:  Choose data units and enter the following:

• (S)  This is the size of the file or data object being transfered.
• (M)  Choose the transfer media (see Transfer Media table below).

Transfer Time:  The calculator returns the duration of the transfer (T) in seconds.  However, this can be automatically converted to other time units (e.g. minutes, hours, days, months) via the pull-down menu.

The Math / Science

Have you ever wondered how long it would take to transfer a file over a network or a hardware device?  Well this handy calculator should help.

Here is a table of transfer rates that are used by the equation.  Not all are implemented.
