The factor used here is the defined value: 1 TB = 1000 GB. Results are rounded to six significant digits for readability, so for high-precision work use the full factor. This converter uses decimal (SI) units — 1 TB = 1,000 GB — as printed on drive boxes. The binary tebibyte (TiB) used by Windows is about 10% larger, which explains the "missing" space on new drives. This converter uses decimal (SI) units — 1 GB = 1,000 MB — the convention drive makers and data plans use. Windows reports binary gibibytes (1 GiB = 1,024 MiB), which is why a "500 GB" drive shows as about 465 GB there.
