Data Storage Converter
Convert between bytes, KB, MB, GB, TB and more
Convert between digital storage units — bytes, kilobytes, megabytes, gigabytes, terabytes, and more. Byte-based units (KB, MB, GB) use the binary convention (1,024-based), while bit-based units (kilobits, megabits) use the decimal convention (1,000-based).
1 Gigabytes (GB) =
1,024
Megabytes (MB)

Real-World Examples
1 gigabyte
Using the binary convention, 1 GB equals 1,024 MB; in the decimal convention used by drive makers, it's 1,000 MB.
500 megabytes
500 MB equals 0.5 GB in decimal terms, or about 0.466 GiB in binary terms.
Frequently Asked Questions
Why does my drive show less space than advertised?
Drive makers usually use decimal units (1 GB = 1,000 MB), while computers show binary units (1 GiB = 1,024 MiB). That gap makes a drive appear smaller in your operating system.
What's the difference between MB and MiB?
MB is decimal (1,000,000 bytes); MiB is binary (1,048,576 bytes). They're close but not identical.
How big is a terabyte?
A terabyte is 1,000 gigabytes (decimal) or about 931 GiB (binary) — enough for hundreds of hours of video.
Important Disclaimer
Uses standard conversion factors. Decimal and binary conventions differ, which is why reported capacity can vary.
