Digital Storage Converter
Digital storage measures an amount of information. The basic unit is the bit; eight bits make a byte. Two prefix systems are in use: decimal SI prefixes, where a kilobyte is 1,000 bytes, and binary IEC prefixes, where a kibibyte is 1,024 bytes.
1 Megabyte = 0.001 Gigabyte
How to convert Megabyte to Gigabyte
One Megabyte equals 0.001 Gigabyte, so multiply any value in MB by 0.001 to get GB. To convert back, divide by 0.001 — or multiply by 1,000.
GB = MB × 0.001
Example: 25 MB × 0.001 = 0.025 GB.
Watch out: Drive manufacturers quote capacity in decimal units, while many operating systems report binary units. That is why a drive sold as 1 TB appears as about 931 GiB once installed — nothing is missing.
