Convert data storage units — bytes, KB, MB, GB, TB, PB.
| Unit | Name | Value |
|---|---|---|
| bit | Bit | 8589934600 |
| B | Byte | 1073741800 |
| KB | Kilobyte | 1048576 |
| MB | Megabyte | 1024 |
| TB | Terabyte | 0.00097657283 |
| PB | Petabyte | 9.5369541e-7 |
Formula: Terabyte = Gigabyte × 0.001
Multiply any gigabyte value by 0.001 to get terabyte. One gigabyte equals 0.001 TB.
Reverse: Gigabyte = Terabyte × 1000
Common gigabyte values with real-world context — factor: 1 GB = 0.001 TB
| Gigabyte (GB) | Terabyte (TB) | Context |
|---|---|---|
| 0.001 GB | 1.000e-06 TB | 1 MB photo |
| 0.01 GB | 1.000e-05 TB | MP3 song |
| 0.1 GB | 0.0001 TB | Short video |
| 1 GB | 0.001 TB | HD movie |
| 4 GB | 0.004 TB | 4K movie |
| 8 GB | 0.008 TB | 8 GB USB drive |
| 16 GB | 0.016 TB | 8 GB USB drive |
| 32 GB | 0.032 TB | Large game |
| 64 GB | 0.064 TB | Large game |
| 128 GB | 0.128 TB | Phone storage |
| 256 GB | 0.256 TB | 256 GB SSD |
| 500 GB | 0.5 TB | 500 GB drive |
| 1,000 GB | 1 TB | 1 TB drive |
| 2,000 GB | 2 TB | 2 TB NAS |
| 8,000 GB | 8 TB | 8 TB enterprise |
GB ÷ 1,000 = TB (decimal). 500 GB = 0.5 TB.
1,000 GB = 1 TB, 2,000 GB = 2 TB, 4,000 GB = 4 TB.
TB × 1,000 = GB.
Specifies app download sizes, database backup sizes, and API payload limits in GB.
Compares phone, tablet, and laptop storage in GB when purchasing devices.
Provisions storage buckets, database sizes, and VM disk images in GB.
Estimates project sizes — 1 minute of 4K RAW video uses about 6 GB.
Monitors disk usage, quota limits, and backup sizes across GB-scale storage.
Handles dataset sizes in GB for training, validation, and test splits.
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.
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.
Converting gigabyte to terabyte 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 GB = 0.005 TB and 10 GB = 0.01 TB. For larger quantities, 100 GB = 0.1 TB. The reverse conversion uses the factor 1000, so 1 TB = 1000 GB. 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 GB = 0.001 TB, calculated with IEEE 754 double-precision arithmetic accurate to at least 8 significant figures.
