What these units are
Terabytes (TB). A terabyte here is 1,024 gigabytes. It is used for hard drives, backups and archives; a terabyte holds roughly 250,000 photos or 250 hours of video.
Bytes (B). A byte is eight bits and normally holds one character of text. It is the base unit for file sizes, memory and storage, and the unit your file manager reports.
Binary and decimal definitions diverge by about 2.4% at kilo and 7.4% at tera. This converter is binary throughout, so it will not match a manufacturer's decimal specification exactly.
Checking a terabytes to bytes conversion
A data conversion looks like the metric chain but is not: this converter uses binary steps, so a kilobyte is 1,024 bytes and a megabyte is 1,024 kilobytes, which is what an operating system reports for a file.
The same names are also used in a decimal system of 1,000, and the gap compounds as the units grow. It is why a drive sold at a round decimal capacity shows less in a file manager, and why a bundle described in decimal gigabytes delivers fewer binary gigabytes than the number suggests.
Checking a data conversion means deciding which definition the number came from before doing the arithmetic. A figure of 500 GB is exact under one definition and about 465 GiB under the other, and no amount of rounding makes those the same quantity.
