Terabytes to Gigabytes
A terabyte is 1,000 gigabytes, the typical size for hard drives and cloud storage plans today. A gigabyte is 1,000 megabytes, the standard unit for phone storage, video files, and monthly data plans. 1 TB equals 1,000 GB, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to data, measured here against data's base unit (bit) — every other data unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
GB = TB × 1,000
TB = GB × 0.001
Worked example: 5 TB × 1,000 = 5,000 GB.
