MB to GB Converter

In binary units there are 1024 MB in 1 GB, because each step from kilobyte to megabyte to gigabyte multiplies by 1024. In the decimal system some drive makers use, 1 GB is 1000 MB instead.

Divide the megabytes by 1024, so GB equals MB divided by 1024. For example 512 MB divided by 1024 is 0.5 GB, and 2048 MB divided by 1024 is 2 GB. To go back, multiply gigabytes by 1024.

One megabyte is 1 divided by 1024, which is 0.0009765625 GB. The converter rounds the display to six decimals, giving 0.000977, while the full precision value is kept for the math behind it.

Binary counts in powers of 1024, which is two to the tenth and how operating systems and memory work. Decimal counts in powers of 1000 and reads more simply on packaging. This tool uses 1024, so 2048 MB is exactly 2 GB.

Storage makers usually print capacity in decimal GB where 1 GB is 1000 MB, but your operating system reports in binary where 1 GB is 1024 MB. The same drive looks smaller in the system even though no space has gone missing.

No. A capital B means bytes and a lowercase b means bits, and one byte is eight bits. This tool converts megabytes to gigabytes. Network speeds are often quoted in megabits, which are eight times smaller than megabytes.

512 MB is 0.5 GB, 1024 MB is 1 GB, 2048 MB is 2 GB, 5120 MB is 5 GB, and 10240 MB is 10 GB. The reference table on the page lists the smaller everyday values too.

Type your gigabytes into the right-hand box here and the MB box updates, or use the dedicated GB to MB tool. Either way, gigabytes times 1024 gives the number of megabytes.
