Digital Storage and Data Converters
Digital Storage Capacity and Memory Calculators
Convert digital data units across computer storage, RAM specifications, cloud backup plans, and bandwidth calculations. Understand differences between decimal storage (base 10) and binary computer memory (base 2).
Supported Units of Storage
- Bytes (B), Kilobytes (KB), Megabytes (MB), Gigabytes (GB), Terabytes (TB), Petabytes (PB)
Popular Digital Storage Conversions
| Conversion Pair | Decimal (Base 10) | Binary / OS (Base 2) | Context |
|---|---|---|---|
| Gigabytes to Terabytes | 1,000 GB = 1 TB | 1,024 GiB = 1 TiB | Hard drives, SSD upgrades |
| Megabytes to Gigabytes | 1,000 MB = 1 GB | 1,024 MiB = 1 GiB | Mobile data limits, video file sizes |
| Terabytes to Petabytes | 1,000 TB = 1 PB | 1,024 TiB = 1 PiB | Enterprise cloud data centers, NAS arrays |
Frequently Asked Questions
Why does my 1TB hard drive show as only ~931GB in Windows?
Drive manufacturers sell capacity in decimal base-10 (1 TB = 1,000,000,000,000 bytes), but operating systems like Windows calculate capacity in binary base-2 (1 TiB = 1,099,511,627,776 bytes).
How many megabytes are in a gigabyte?
In the SI decimal standard, 1 GB = 1,000 MB. In binary RAM/OS memory, 1 GiB = 1,024 MiB.
