Gigabytes to Gibibytes
A gigabyte is 1,000 megabytes, the standard unit for phone storage, video files, and monthly data plans. A gibibyte is 1,024 mebibytes, the binary unit typically used to report RAM capacity precisely. 1 GB equals ≈0.931323 GiB, 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
GiB = GB × ≈0.931323
GB = GiB × ≈1.07374
