Conversion Formula
GB = MB ÷ 1000 (decimal, SI standard) GB = MB ÷ 1024 (binary, traditional computing) Operating systems differ: Windows historically used 1 GB = 1024 MB (binary) macOS (since 10.6) uses 1 GB = 1000 MB (decimal) Storage manufacturers always use decimal (1 GB = 1000 MB) Examples: 100 MB = 0.1 GB (a small app) 1000 MB = 1 GB (decimal, exact) 1024 MB = 1 GiB (binary gibibyte)
Frequently Asked Questions
How many GB is 1000 MB?
1000 MB equals exactly 1 GB in the decimal (SI) system used by storage manufacturers and macOS. In the binary system used by older Windows versions, 1024 MB = 1 GiB (gibibyte). Most modern contexts use the decimal definition.
How many MB is 1 GB?
In decimal terms, 1 GB = 1000 MB. In binary terms, 1 GiB = 1024 MiB. Hard drive manufacturers and cloud storage services use decimal — so a '500 GB' drive contains 500,000 MB.
Why does my 1 TB drive show less than 1000 GB in Windows?
Storage manufacturers measure 1 TB as 1,000,000,000,000 bytes (decimal). Older Windows versions report storage in gibibytes (GiB = 1,073,741,824 bytes), which makes the drive appear about 9% smaller. A '1 TB' drive shows as ~931 GB in older Windows.
