What this converter does
This converter turns terabytes into gigabytes and back, and covers MB, KB, bytes and the binary units (KiB, MiB, GiB, TiB). Drive capacity is decimal, so 1 TB equals 1,000 GB. Type a value and read the result instantly.
The decimal-versus-binary difference is why a “1 TB” drive appears as roughly 931 GiB in your operating system. This tool handles both, per NIST.
02
The units it covers
Storage converts through the byte. Decimal units (KB/MB/GB) step by 1,000; binary units (KiB/MiB/GiB) step by 1,024.
View all units & their values
| Unit | Symbol | Value | Mainly used |
|---|---|---|---|
| Byte | B | 1 | Base unit |
| Kilobyte | KB | 1,000 | Decimal |
| Megabyte | MB | 1,000,000 | Decimal |
| Gigabyte | GB | 1e9 | Drive & file sizes |
| Gibibyte | GiB | 1,073,741,824 | Binary (RAM, OS) |
| Terabyte | TB | 1e12 | Disk capacity |
03
The formula
Each unit has a fixed value in bytes, so any conversion goes through the byte once:
Conversion
result = value × factor_from ÷ factor_toWhere:
- value = the number you typed
- factor_from = the “from” unit’s value in bytes
- factor_to = the “to” unit’s value in bytes

Worked example
Convert 2 TB to GB.
Step 1 · The factor
1 TB = 1,000 GBStep 2 · Multiply
2 × 1000 = 2,000 GBSo a 2 TB drive is 2,000 GB.

The units in this example
Terabytesymbol: TB
The decimal unit for disk capacity — one trillion bytes.
Common storage conversions
- 1 TB = 1,000 GB
- 1 TB = 1e6 MB
- 1 TB ≈ 0.909 TiB
- 1 TB ≈ 931 GiB
Gigabytesymbol: GB
The decimal unit for file and drive sizes — one billion bytes.
Common storage conversions
- 1 GB = 1,000 MB
- 1 GB = 0.001 TB
- 1 GB ≈ 0.931 GiB
- 1,000 GB = 1 TB
