Full origin of MB →Frequently Asked Questions
What is the difference between MB and Mb?
Capital B means bytes and lower-case b means bits, and there are eight bits in a byte. So 100 Mb per second of broadband delivers roughly 12.5 MB of files per second.
How many MB are in a GB?
1,024 MB in a gigabyte when counted in binary, or 1,000 MB under the decimal system that storage manufacturers and network operators use. That difference is why a drive sold as 500 GB shows up as slightly less on your computer.
What does mb mean in a text message?
In casual messaging, lower-case "mb" is usually short for "my bad", a quick way of admitting a small mistake. Context makes it clear, since nobody apologises in megabytes.
