Data Storage Converter

Divide the number of megabytes by 1024 (binary) or 1000 (decimal). This converter uses binary calculations where 1 GB = 1024 MB.

Yes. The converter explicitly distinguishes between KiB/MiB/GiB (binary, powers of 1024, per the IEC 60027-2 standard used by most operating systems) and KB/MB/GB (decimal, powers of 1000, per the SI standard used by hard-drive manufacturers). A 500GB drive correctly shows as ~465.66 GiB — the two values are both accurate, just expressed in different unit systems.

Yes. The converter is fully responsive and works on iOS Safari, Android Chrome, and all other modern mobile browsers. The binary/decimal toggle, the unit dropdowns from bits through exabytes, and the live conversion result are all touch-sized. No horizontal scrolling is needed at any screen size down to 320px wide.

No. The Data Storage Converter is free to use with no signup, no paywall, and no ads that require your data. All conversions between bits, bytes, KB/KiB, MB/MiB, GB/GiB, and TB/TiB (both binary and decimal conventions) run in your browser. Use it as often as you need without any limits.

Hard drive manufacturers measure in decimal (1 GB = 1,000,000,000 bytes) while operating systems measure in binary (1 GB = 1,073,741,824 bytes). A '500 GB' drive contains 500,000,000,000 bytes, which your OS reports as approximately 465 GiB. This is not missing space — it is a difference in how the same bytes are counted.

Lowercase 'b' stands for bits; uppercase 'B' stands for bytes. One byte equals eight bits. Internet speeds are usually quoted in Mbps (megabits per second), while file sizes are usually quoted in MB (megabytes). A 100 Mbps connection transfers approximately 12.5 MB per second.
