About Terabytes to Gigabytes
Convert terabytes to gigabytes instantly, with a reference table of common values. The factor is exact: 1 TB = 1024 GB.
The conversion that explains the most common storage complaint: a drive sold as 1 TB shows as roughly 931 GB, because the manufacturer counted in decimal and the operating system in binary.
A terabyte is a thousand gigabytes. Here the decimal-versus-binary gap reaches about 10%, which is why a drive sold as 1 TB is reported by many operating systems as roughly 931 GB โ nothing is missing, the two are simply counting differently. It is the unit for hard drives, backup storage and the working datasets of small organisations. A 1 TB drive holds roughly 250,000 photographs, or about 300 hours of high-definition video.
Worked through with real numbers: 1 TB is 1024 GB, 8 TB is 8192 GB, 64 TB is 65536 GB.
As for the other side of the conversion: an hour of high-definition video is roughly 3 GB, and a modern phone typically holds 128 to 512 GB.
Digital storage has two competing conventions. The SI definition makes a kilobyte 1,000 bytes; the binary convention used by much software makes it 1,024, properly called a kibibyte. The gap compounds at every step, reaching about 10% by the terabyte โ which is why a drive sold as 1 TB shows as roughly 931 GB.
