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: Kilobyte = Gigabyte × 1,000,000
Multiply any gigabyte value by 1,000,000 to get kilobyte. One gigabyte equals 1,000,000 KB.
Reverse: Gigabyte = Kilobyte × 1.0000e-6
Common gigabyte values with real-world context — factor: 1 GB = 1,000,000 KB
| Gigabyte (GB) | Kilobyte (KB) | Context |
|---|---|---|

| 8 GB | 8e+06 KB | 8 GB USB drive |
| 16 GB | 1.6e+07 KB | 8 GB USB drive |
| 32 GB | 3.2e+07 KB | Large game |
| 64 GB | 6.4e+07 KB | Large game |
| 128 GB | 1.28e+08 KB | Phone storage |
| 256 GB | 2.56e+08 KB | 256 GB SSD |
| 500 GB | 5e+08 KB | 500 GB drive |
| 1,000 GB | 1e+09 KB | 1 TB drive |
| 2,000 GB | 2e+09 KB | 2 TB NAS |

1 GB = 1,000,000 KB. Memorize this for instant estimates.
Data storage uses both decimal (×1000) and binary (×1024) prefixes. The factor above follows the decimal (SI) standard used by storage manufacturers.
To verify: multiply your result by 1.0000e-6 to recover the original GB value.
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 kilobyte (KB) equals 1,000 bytes in decimal (SI) notation, or 1,024 bytes in binary usage — a distinction that has caused decades of confusion. The SI standard (IEC 80000-13, 1998) formally defined KB as 1,000 bytes, reserving KiB for 1,024 bytes.
Kilobytes were the standard measure for file sizes in the early PC era (1980s). A floppy disk held 360 KB or 1.44 MB; early email attachments were measured in kilobytes.
Interesting fact: A plain text page of 500 words is about 2-3 KB. The first commercially available hard drive (IBM 350, 1956) stored just 3.75 MB — or about 3,750 KB.
Converting gigabyte to kilobyte 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 = 5,000,000 KB and 10 GB = 10,000,000 KB. For larger quantities, 100 GB = 100,000,000 KB. The reverse conversion uses the factor 1.0000e-6, so 1 KB = 1.0000e-6 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 = 1,000,000 KB, calculated with IEEE 754 double-precision arithmetic accurate to at least 8 significant figures.
