- 8 Kilobits (Kb) = 1 Kilobyte (KB)
8 Megabits (Mb) = 1 Megabyte (MB)
KB and MB are measurements of data file sizes and storage.
- Kbps and Mbps are short for "Kilobits per second" and "Megabits per second" and are measurements of data transfer rates (also known as connection speed).
- To estimate how long it would take to download a large file based upon your connection speed, you can use the following simple mathematical equation:(Convert file size to Mb) / coneection speed (in Mbps) = # of seconds to complete download.
So if your connection speed is 16 Mbps then, then you could theoretically download a 2 MB file, such as a high-resolution digital photo, in approximately one second.
(2 MB x 8 Mb) / 16 Mbps = 1 second
