Convert gibibit per second to megabyte per second

Common mistakes

• Broadband's '100 Mbit/s' is megabits, not megabytes: divide by 8 for the download rate in MB/s. 100 Mbit/s gives about 12.5 MB/s, so a 1 GB file takes over a minute, not ten seconds.
• MB/s (bytes) and Mb/s (bits) differ by a factor of 8, and the letter case is the only visible difference. Gigabit networking at 1 Gbit/s moves 125 MB/s of file data. Always check whether a spec uses the big or the small b.
• Network speeds always count in decimal: 1 kbit/s = 1,000 bit/s and 1 Mbit/s = 1,000,000 bit/s. Binary prefixes (Kibit/s, Mibit/s, based on 1,024) are a different scale mostly seen in download managers. Don't mix the scales when comparing measured speed against what your ISP promised.
