How do you convert GB to MB?
Multiply the gigabyte value by 1,000 to get megabytes in the decimal system used for storage and bandwidth: MB = GB × 1000. In the binary system the units differ - 1 GiB = 1,024 MiB.
Worked example
2 GB is 2 × 1000 = 2,000 MB. A 64 GB phone is 64 × 1000 = 64,000 MB, and 500 MB is 0.5 GB.
