Gigabytes (10^9 B) to Terabytes (10^12 B) Converter
1 GB equals 0.001 TB, and 1 TB equals 1,000 GB. Enter a value in either box to convert gigabytes (10^9 b) to terabytes (10^12 b) and back. Formula: bits = value x unit factor (decimal: 1 kB = 1,000 B; binary: 1 KiB = 1,024 B; 1 byte = 8 bits).

Worked example: 10 GB = 0.01 TB. A drive sold as 500 GB holds 500 x 10^9 bytes, which is 500,000,000,000 / 1,073,741,824 = 465.66 GiB.

Formula
bits = value x unit factor (decimal: 1 kB = 1,000 B; binary: 1 KiB = 1,024 B; 1 byte = 8 bits)Understanding Data Storage Conversion
Two systems share the same abbreviations in everyday talk. Decimal units follow SI prefixes: a kilobyte is 1,000 bytes and a gigabyte is 10^9 bytes. Binary units, standardized by the IEC as kibibyte, mebibyte and gibibyte, count in powers of 1,024. Drive makers advertise decimal gigabytes, while many operating systems report binary ones, which is why a "500 GB" drive appears as roughly 465 GiB.
Tips and Best Practices
- 1Divide a decimal GB figure by 1.0737 to get GiB.
- 2RAM is normally sold in binary multiples, while disk and network sizes use decimal.
- 3A byte is 8 bits; lowercase b means bits and uppercase B means bytes.
Real-World Example
A drive sold as 500 GB holds 500 x 10^9 bytes, which is 500,000,000,000 / 1,073,741,824 = 465.66 GiB.
Common Mistakes to Avoid
- Mixing bits and bytes, which is an eight-fold error.
- Treating a kilobyte as always 1,024 bytes; under SI it is 1,000.
- Expecting a new drive to show its full advertised size in the operating system.
How to Use
- Type a number in the Gigabytes (10^9 B) box.
- The Terabytes (10^12 B) result appears instantly; you can also edit the Terabytes (10^12 B) box to convert backwards.
- Use the swap button to reverse the direction and Copy result to copy the answer.
