Convert data storage units — bytes, KB, MB, GB, TB, PB.
| Unit | Name | Value |
|---|---|---|
| bit | Bit | 8.796000e+12 |
| B | Byte | 1.099500e+12 |
| KB | Kilobyte | 1073730500 |
| MB | Megabyte | 1048564.9 |

Formula: Gigabyte = Terabyte × 1000
Multiply any terabyte value by 1000 to get gigabyte. One terabyte equals 1000 GB.
Reverse: Terabyte = Gigabyte × 0.001
Common terabyte values with real-world context — factor: 1 TB = 1000 GB
| Terabyte (TB) | Gigabyte (GB) | Context |

TB × 1,000 = GB (decimal). 2 TB = 2,000 GB.
1 TB = 1,000 GB = 1,000,000 MB.
GB ÷ 1,000 = TB.
Configures RAID arrays and backup schedules for TB-scale storage systems.
Archives finished film projects in TB.
Manages production database sizes in TB.
Calculates CCTV storage — 1 TB per camera per week at 4K.
Plans rack-level storage in TB for enterprise workloads.
Images and analyzes hard drives of 1-8 TB.
The terabyte (TB) equals 1,000 GB (decimal) or 1,099,511,627,776 bytes (binary). Consumer hard drives crossed the 1 TB threshold in 2007, and TB-scale storage is now standard in laptops and desktop computers.
Terabytes define large personal and enterprise storage. A 1 TB drive holds approximately 200,000 photos, 250,000 MP3 songs, or 500 hours of HD video.
Interesting fact: The entire printed collection of the US Library of Congress is estimated at about 10 TB of text data. The global internet traffic in 2022 was approximately 4.8 exabytes (4,800,000 TB) per day.
The gigabyte (GB) equals 1,000,000,000 bytes (decimal) or 1,073,741,824 bytes (binary). The distinction matters: Windows historically reported drive sizes in binary gigabytes, while drive manufacturers used decimal — causing the perennial 'missing space' confusion.
Gigabytes define modern consumer storage: smartphone apps, photos, and videos. A typical smartphone photo is 3-5 MB, so 1 GB holds roughly 200-300 photos. A 4K movie takes 60-100 GB.
Interesting fact: The first 1 GB hard drive (IBM 3380, 1980) weighed 250 kg and cost $40,000. Today, a 1 GB microSD card costs about $0.10.
Converting terabyte to gigabyte is a common task in computing, networking, and data management. Storage manufacturers, operating systems, and network equipment often express data sizes in different units — understanding the conversion is essential for comparing specifications, planning storage capacity, and interpreting network speed versus file size relationships.
As a practical reference: 5 TB = 5000 GB and 10 TB = 10,000 GB. For larger quantities, 100 TB = 100,000 GB. The reverse conversion uses the factor 0.001, so 1 GB = 0.001 TB. Note that decimal prefixes (KB=1,000, MB=1,000,000) differ from binary prefixes (KiB=1,024, MiB=1,048,576) — always check which standard your software or hardware uses.
All conversions use the internationally recognized factor of exactly 1 TB = 1000 GB, calculated with IEEE 754 double-precision arithmetic accurate to at least 8 significant figures.
