How to convert terabytes to gibibytes
Formula: GiB = TB × 931.323
Worked example: 2 TB → 2 × 931.323 = 1,862.65 GiB
One terabyte is about 931.3 GiB. A drive sold as 1 TB therefore shows about 931 GB in Windows File Explorer, and 1 TB in macOS, which counts in decimal units.

What is a terabyte?
The terabyte is one trillion bytes, or 1,000 GB. Hard drives, SSDs and cloud backups are sold in TB. A 1 TB drive holds about 250,000 photos of 4 MB.
What is a gibibyte?
The gibibyte is 1,073,741,824 bytes, or 1,024 MiB, about 7.4% larger than a gigabyte. RAM modules are binary: a stick sold as 16 GB actually holds 16 GiB. Windows also shows disk sizes in GiB while labeling them GB.
