Convert data storage units — bytes, KB, MB, GB, TB, PB.
| Unit | Name | Value |
|---|---|---|
| bit | Bit | 9.007000e+15 |
| B | Byte | 1.125875e+15 |
| KB | Kilobyte | 1.099487e+12 |
| MB | Megabyte | 1073718100 |
| GB | Gigabyte | 1048552.8 |
| TB | Terabyte | 1023.9882 |
Formula: Gigabyte = Petabyte × 1,000,000
Multiply any petabyte value by 1,000,000 to get gigabyte. One petabyte equals 1,000,000 GB.
Reverse: Petabyte = Gigabyte × 1.0000e-6
Common petabyte values with real-world context — factor: 1 PB = 1,000,000 GB
| Petabyte (PB) | Gigabyte (GB) | Context |
|---|---|---|
| 0.001 PB | 1,000 GB | 1 TB drive |
| 0.01 PB | 1e+04 GB | 10 TB NAS |
| 0.1 PB | 1e+05 GB | 100 TB server |
| 1 PB | 1e+06 GB | 1 PB data center |
| 5 PB | 5e+06 GB | 5 PB major cloud |
| 10 PB | 1e+07 GB | LHC annual data |
| 50 PB | 5e+07 GB | 50 PB hyperscale |
| 100 PB | 1e+08 GB | Large cloud infra |
| 500 PB | 5e+08 GB | Major cloud region |
| 1,000 PB | 1e+09 GB | 1 EB |
| 5,000 PB | 5e+09 GB | 5 EB internet traffic |
| 1e+04 PB | 1e+10 GB | 10 EB monthly traffic |
| 1e+05 PB | 1e+11 GB | Global daily traffic |
| 1e+06 PB | 1.000e+12 GB | 1 ZB global data |
| 1e+09 PB | 1.000e+15 GB | All human data |
1 PB = 1,000,000 GB. 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 PB 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 petabyte (PB) equals 1,000 TB (decimal) or 2^50 bytes (binary). Petabyte-scale storage is the domain of large cloud providers, government agencies, and scientific research projects.
Facebook processes over 100 PB of data per month. The Large Hadron Collider at CERN generates about 15 PB of data per year. The human genome project required about 200 PB of data analysis.
Interesting fact: If you stored 1 PB of data on standard DVDs, the stack would be about 220 km tall. Google processes approximately 20 PB of data 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 petabyte 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 PB = 5,000,000 GB and 10 PB = 10,000,000 GB. For larger quantities, 100 PB = 100,000,000 GB. The reverse conversion uses the factor 1.0000e-6, so 1 GB = 1.0000e-6 PB. 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 PB = 1,000,000 GB, calculated with IEEE 754 double-precision arithmetic accurate to at least 8 significant figures.
