Terabyte to Gigabyte Converter
Digital storage · unit-converter
Convert Terabyte to Gigabyte 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.

From: Terabyte (tb)

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.
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.
How to convert terabytes to gigabytes
1 terabyte is equal to 1000 gigabyte in this tool (values are compared in byte-equivalents):
1 tb = (1,000,000,000,000 B ÷ 1,000,000,000 B) gb = 1000 gb
1 TB = 1,000 GB (decimal terabyte).
Each terabyte counts as 1,000,000,000,000 bytes and each gigabyte as 1,000,000,000 bytes, so one tb equals 1,000,000,000,000 ÷ 1,000,000,000 gb = 1000 gb.
Let d(tb) be the numeric amount in Terabyte (tb), and d(gb) the amount in Gigabyte (gb). Then:
d(gb) = d(tb) × (1,000,000,000,000 / 1,000,000,000)
Equivalently, divide by how many tb fit into one gb (bytes per gb divided by bytes per tb):
d(gb) = d(tb) ÷ 0.001
Or: gigabyte = terabyte ÷ 0.001
Examples
Example #1: Convert 1 tb to gigabyte
1 tb = 1 tb × (1,000,000,000,000/1,000,000,000) gb = 1000 gb
1 tb = 1 tb ÷ 0.001 = 1000 gb
Example #2: Convert 10 tb to gigabyte
10 tb = 10 tb × (1,000,000,000,000/1,000,000,000) gb = 10000 gb
10 tb = 10 tb ÷ 0.001 = 10000 gb
Summary
To convert Terabyte to Gigabyte, multiply the value in tb by the ratio of bytes per tb divided by bytes per gb. Equivalently: value_gb = value_tb × (1000000000000 / 1000000000). Numerically, 1 tb equals 1000 gb.
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 Terabyte to Gigabyte is 1.000000e+3 (1 tb = 1000 gb).
