TB to GB Calculator

In the decimal system, 1 TB = 1,000 GB exactly. In the binary system, 1 TiB = 1,024 GiB. Drive manufacturers use decimal, so a 1 TB hard drive contains 1,000 decimal gigabytes.

A terabyte contains 1,000 gigabytes using the decimal standard. If your operating system reports binary values, it shows approximately 931 GiB for a 1 TB drive because 1,000,000,000,000 bytes divided by 1,073,741,824 equals roughly 931.

Your drive actually holds 2,000,000,000,000 bytes (2 TB decimal). The operating system displays binary gibibytes, dividing by 1,024 three times. The result is about 1,862 GiB, which the OS labels as "GB." Both numbers describe the same physical storage.

TB (terabyte) is the decimal unit equal to 10^12 bytes (1,000,000,000,000). TiB (tebibyte) is the binary unit equal to 2^40 bytes (1,099,511,627,776). TiB is about 9.95% larger than TB. The IEC introduced TiB to eliminate the ambiguity.

Use the decimal system (multiply by 1,000). Cloud providers like Google Drive, iCloud, and Dropbox all advertise storage in decimal units. So 2 TB of cloud storage gives you 2,000 GB.

In binary, 1 TiB = 1,024 GiB. This is the value your operating system typically uses when reporting available disk space. For most consumer purposes, the decimal answer of 1,000 GB per TB is simpler and more commonly referenced.
