Marketing often uses decimal SI steps (1,000); operating systems often use binary steps (1,024). This guide explains both, with formulas, tables, and converter links.

No sign-up required. ## What data storage conversion is (and why sizes “shrink”) Storage conversion rewrites a quantity of digital information in another unit: bits, bytes, KB/MB/GB/TB (decimal) or KiB/MiB/GiB/TiB (binary). A “1 TB” drive advertised with decimal terabytes holds 1,000,000,000,000 bytes, about 0.91 TiB in binary, which is why the OS can show a smaller number than the box. Bits vs bytes matter too: 1 byte = 8 bits. Confusing them understates or overstates capacity by a factor of eight. ## Plain-language storage formulas - Bits ↔ bytes: divide bits by 8 for bytes. Multiply bytes by 8 for bits. - Decimal (SI) steps: each step × 1,000 (KB → MB → GB → TB). - Binary (IEC) steps: each step × 1,024 (KiB → MiB → GiB → TiB). - GB (decimal) → bytes: multiply by 1,000,000,000. - GiB → bytes: multiply by 1,073,741,824 (1024³). When a vendor does not say which system they use, assume marketing labels are decimal and OS file browsers are often binary, then convert explicitly. ## Data storage conversion tables ### Decimal storage steps Unit Bytes (exact decimal) 1 KB 1,000 1 MB 1,000,000 1 GB 1,000,000,000 1 TB 1,000,000,000,000 ### Binary storage steps Unit Bytes 1 KiB 1,024 1 MiB 1,048,576 1 GiB 1,073,741,824 1 TiB 1,099,511,627,776 ## Worked examples ### Example 1, photo library in GB A folder is **4,800 MB** (decimal). In GB: 4,800 ÷ 1,000 = **4.8 GB**. ### Example 2, drive label vs OS A drive is sold as **2 TB** decimal = 2,000,000,000,000 bytes. In GiB: 2,000,000,000,000 ÷ 1,073,741,824 ≈ **1,862.6 GiB** (~1.86 TiB). ### Example 3, bits on a datasheet A chip lists **64 Gbit**. In bytes: 64 ÷ 8 = **8 GB** (decimal gigabits → gigabytes when using the same SI prefix scale). ## Common data storage mistakes - Assuming KB always means 1,024, many specs now use KiB for binary and KB for decimal. - Comparing cloud quotas in GB to OS sizes in GiB without converting. - Mixing bits and bytes on network or media labels. - Rounding mid-pipeline when estimating how many files fit on a card. ## Data storage converter tools Start with the [Data Storage Converter](https://shoutingnow.com/tools/data-storage-converter/), or jump to a dedicated pair: - Gigabytes to Bits Converter - Gigabytes to Bytes Converter - Kilobytes to Gigabytes Converter - Megabytes to Gigabytes Converter - Megabytes to Kilobytes Converter - Terabytes to Bits Converter - Terabytes to Gigabytes Converter - Terabytes to Kilobytes Converter ## Related reading - Data transfer rate guide, Mbps vs MB/s for downloads - Unit conversion chart & calculator guide, full category map ## Frequently Asked Questions ### How many bytes are in one gigabyte? In decimal SI labeling, 1 GB equals 1,000,000,000 bytes. In binary, 1 GiB is 1,073,741,824 bytes instead, so check which system whatever label you are reading is actually using. ### Why does my 1 TB drive show less space in the OS? Manufacturers sell drives in decimal TB, but operating systems report space in binary GiB/TiB. 1 TB decimal comes out to about 0.91 TiB, so the capacity did not shrink, the unit system just changed underneath it. ### How do I convert bits to bytes? Divide bits by 8, so 64 Gbit becomes 8 GB on the matching SI prefix scale. The [Data Storage Converter](https://shoutingnow.com/tools/data-storage-converter/) handles mixed pairs if the scales do not match up cleanly. ### What is the difference between MB and MiB? MB usually means 1,000,000 bytes in decimal, while MiB means 1,048,576 bytes in binary. Mixing the two up is exactly what causes that "missing" storage feeling. ### How do I convert megabytes to gigabytes? Divide MB by 1,000 for decimal units, so 4,800 MB becomes 4.8 GB. For binary, divide MiB by 1,024 to get GiB instead. ### Are ShoutingNow storage converters free? They are, the Data Storage Converter and its dedicated pair tools run free with no account required. ```json [{"@context":"https://schema.org","@type":"Organization","name":"ShoutingNow","url":"https://shoutingnow.com/","logo":{"@type":"ImageObject","url":"https://shoutingnow.com/wp-content/themes/shoutingnow-theme/assets/images/logo.png"},"sameAs":["https://x.com/makani20","https://www.linkedin.com/in/makani20/","https://post-see.com"],"contactPoint":{"@type":"ContactPoint","contactType":"customer support","email":"support@shoutingnow.com","url":"https://shoutingnow.com/contact/"},"slogan":"Learn.
