How do you convert GB to MB?
Multiply the number of gigabytes by 1,000. This conversion mainly helps size up a mobile plan: knowing a GB is a thousand MB lets you match the plan against real app consumption, which is usually shown in MB.
MB = GB × 1,000GB = MB ÷ 1,000
Where these two units are used
On one and the same machine, memory is counted in powers of 1024 and the disk in powers of 1000: two different gigabytes live inside the same case. The 1.44 megabyte floppy was neither 1.44 million bytes nor 1.44 times 1024 squared, but 1440 kibibytes: a hybrid of both conventions, and the worst example one can cite.

SI prefixes: 1 GB = 10⁹ bytes = 1,000 MB. Carriers and manufacturers follow this decimal convention. IEC standard 80000-13 sets this decimal definition and reserves the binary prefixes Ki, Mi and Gi for powers of 1024. Methodology & sources.
Frequently asked questions
What does a 20 GB plan actually cover?
Roughly 40 hours of music streaming (150 MB per hour), 7 hours of HD video (3 GB per hour) or 4,000 web pages. Video dominates any plan: dropping the playback quality cuts consumption threefold or more.
Why does my phone show MB while my plan is in GB?
Apps report consumption in MB, more readable for a single session, while the carrier sells a monthly allowance in GB. Dividing by 1,000 puts both on the same scale.
Why is a 20 MB file rejected by a 25 MB limit?
Because email carries attachments in base64, an encoding that uses only printable characters and inflates the file by roughly a third. The 25 MB Gmail advertises applies to the encoded message: divide the limit by 1.37 for the file size actually accepted, a little over 18 MB.
How do I turn a Mb/s bitrate into MB consumed?
Multiply the bitrate by 450: a 5 Mb/s stream uses 2,250 MB per hour, or 2.25 GB. The factor comes from the 3,600 seconds in an hour divided by the 8 bits in a byte. It is the quickest way to size a plan: at 5 Mb/s, 20 GB lasts under nine hours.
Were the 700 MB CD and the 1.44 MB floppy telling the truth?
Neither one, in decimal terms. An 80-minute CD holds 737,280,000 bytes, so 737 decimal MB, advertised as 700 MB because it was counted in mebibytes. The floppy is stranger still: its 1,474,560 bytes are 1,440 KiB, which makes its megabyte worth 1,024,000 bytes, the only computing unit that mixes both bases.
How do I convert GB to MB?
Multiply by 1000. A 2 GB file is 2000 MB, and a 0.5 GB one is 500 MB. If a device shows 1024 instead, it is counting in mebibytes and writing MB, the same confusion that makes a 1 TB drive read 931 GB.
