MB to GB Converter
Free MB to GB converter — megabytes to gigabytes using the binary standard (1024 MB = 1 GB). Instant two-way conversion, no signup.
About the MB to GB Converter
Convert megabytes to gigabytes instantly using the binary standard: 1 GB = 1024 MB, so GB = MB ÷ 1024. That matches how Windows, macOS file listings and most software report sizes. Enter megabytes and get gigabytes at once — or type GB to convert back.
Common scenarios: adding up app downloads in MB against the GB free on a phone, checking how much of a 10 GB data plan a 750 MB update will eat (about 7.3%), sizing email attachments, or working out how many 350 MB episodes fit on a 32 GB card (roughly 93).
Storage marketing uses the decimal standard instead (1 GB = 1000 MB), which is why advertised capacities look bigger than what your OS shows. This tool follows the binary convention; divide by 1000 if you need the decimal reading.

Frequently Asked Questions
How many MB make 1 GB?
1,024 MB make 1 GB in the binary standard used by operating systems. Storage manufacturers and mobile carriers often use the decimal standard, where 1,000 MB = 1 GB. This converter uses 1,024.
Is 500 MB the same as 0.5 GB?
Not quite, in binary terms: 500 MB ÷ 1024 = 0.4883 GB. Half a binary gigabyte is 512 MB. In decimal terms, 500 MB is exactly 0.5 GB.
How many GB is 10,000 MB?
10,000 MB is 9.7656 GB (binary). In decimal units it would be exactly 10 GB — the gap between the two standards grows with size.
How many 100 MB files fit in 1 GB?
Ten files of 100 MB total 1,000 MB, which is just under 1 GB (1,024 MB) — so ten fit with 24 MB to spare. In practice filesystem overhead shaves a little off usable space.
Why does my phone's storage math never add up exactly?
Three reasons: the OS counts in binary (1024) while packaging uses decimal (1000), the operating system itself occupies several GB, and filesystem structures consume space. Converting everything to one standard — as this tool does — makes comparisons consistent.
