Gigabyte to Terabyte Converter
Digital storage · unit-converter
Convert Gigabyte to Terabyte with fixed input and output units, a step-by-step formula line, and reference tables. This hub uses decimal byte units (kB, MB, GB, …) and decimal megabits; the main converter also includes binary (KiB, MiB, …) units.

About Gigabyte
The gigabyte (GB) here is a decimal unit: 1 GB = 10⁹ bytes. Storage marketing and many OS dialogs use decimal GB; some systems still show binary (GiB) labels—check context when comparing numbers.
About Terabyte
The terabyte (TB) is 10¹² bytes in this tool (decimal SI). Large drives and cloud tiers are usually quoted in TB using powers of ten.
How to convert gigabytes to terabytes
1 gigabyte is equal to 0.001 terabyte in this tool (values are compared in byte-equivalents):
1 gb = (1,000,000,000 B ÷ 1,000,000,000,000 B) tb = 0.001 tb
Each gigabyte counts as 1,000,000,000 bytes and each terabyte as 1,000,000,000,000 bytes, so one gb equals 1,000,000,000 ÷ 1,000,000,000,000 tb = 0.001 tb.
Let d(gb) be the numeric amount in Gigabyte (gb), and d(tb) the amount in Terabyte (tb). Then:
d(tb) = d(gb) × (1,000,000,000 / 1,000,000,000,000)
Equivalently, divide by how many gb fit into one tb (bytes per tb divided by bytes per gb):
d(tb) = d(gb) ÷ 1000
Or: terabyte = gigabyte ÷ 1000
Examples
Example #1: Convert 1 gb to terabyte
1 gb = 1 gb × (1,000,000,000/1,000,000,000,000) tb = 0.001 tb
1 gb = 1 gb ÷ 1000 = 0.001 tb
Example #2: Convert 10 gb to terabyte
10 gb = 10 gb × (1,000,000,000/1,000,000,000,000) tb = 0.01 tb
10 gb = 10 gb ÷ 1000 = 0.01 tb
Summary
To convert Gigabyte to Terabyte, multiply the value in gb by the ratio of bytes per gb divided by bytes per tb. Equivalently: value_tb = value_gb × (1000000000 / 1000000000000). Numerically, 1 gb equals 0.001 tb.
Relationship context
Both units are byte-based units (decimal SI: kB, MB, GB, …). Factors are fixed relative to one byte, so conversions are exact in floating-point arithmetic for this tool. The factor from Gigabyte to Terabyte is 1.000000e-3 (1 gb = 0.001 tb).
