Gigabits to Gigabytes
A gigabit is 1,000 megabits, used to describe fiber internet speeds and network hardware like Gigabit Ethernet. A gigabyte is 1,000 megabytes, the standard unit for phone storage, video files, and monthly data plans. 1 Gbit equals 0.125 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 = Gbit × 0.125
Gbit = GB × 8
Worked example: 5 Gbit × 0.125 = 0.625 GB.
