Gigabyte to Megabyte (Gigabyte to Megabyte)
Result
1,024 Megabyte
Formula
Megabyte = Gigabyte × 1,024
1 Gigabyte = 1,024 Megabyte, and 1 Megabyte = 0.0009765625 Gigabyte.
Storage here uses binary multiples (1 KB = 1,024 bytes, 1 MB = 1,024² bytes), the convention most operating systems use. The IEC names for these are kibibyte (KiB), mebibyte (MiB) and so on. Bandwidth uses decimal SI prefixes (1 Mbit/s = 1,000,000 bit/s).
Worked examples
- 1 Gigabyte × 1,024 = 1,024 Megabyte
- 10 Gigabyte × 1,024 = 10,240 Megabyte
- 100 Gigabyte × 1,024 = 102,400 Megabyte
Common mistakes
- Drive manufacturers use decimal units: a "1 TB" drive holds 10¹² bytes, which an operating system shows as about 931 GB (binary).
- Bits are not bytes: a 100 Mbit/s connection downloads at most 12.5 MB per second (divide by 8), before protocol overhead.
