Most popular data conversions

The most searched data conversions are MB to GB, GB to TB, and bytes to megabytes. One gigabyte is 1,000 megabytes (decimal) and one terabyte is 1,000 gigabytes. Note that operating systems often use binary units (1,024-based), which is why a 1 TB drive shows as about 931 GB.

Understanding data units

Digital storage is measured in bytes and their multiples. Storage manufacturers use decimal units (1 GB = 1,000 MB), while operating systems often report in binary (1 GiB = 1,024 MiB). This converter uses decimal units, matching how storage and bandwidth are sold.

Quick reference

1 KB = 1,000 bytes · 1 MB = 1,000 KB · 1 GB = 1,000 MB · 1 TB = 1,000 GB. Use the converter for any exact value.

Frequently asked questions

Why does my 1 TB drive show only 931 GB?

Manufacturers count decimal bytes (1 TB = 10¹² bytes) while operating systems often display binary units (1 TiB = 2⁴⁰ bytes). The same bytes read as 931 'GB' on the binary scale — no space is missing.

What is the difference between Mbps and MB/s?

Mbps is megabits per second (how internet speed is sold); MB/s is megabytes per second (how downloads display). Divide Mbps by 8: a 300 Mbps line peaks at 37.5 MB/s.

How many photos fit in a gigabyte?

Roughly 200–330 smartphone photos at 3–5 MB each. RAW files from dedicated cameras run 25–50 MB, so only 20–40 fit per gigabyte.
