AI explanation
Formula
Converts via bytes as a common base unit, using decimal (SI, 1000-based) unit definitionsWorked example
1,024 MB to GB
| Field | Value |
|---|---|
| Amount | 1024 |
| From unit | mb |
| To unit | gb |
| Converted value | 1.024 |
Assumptions
- Uses decimal (SI) unit definitions — 1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes, and so on — matching how storage devices are conventionally marketed, rather than the binary (1,024-based) convention some operating systems display.
Frequently asked questions
Why does my OS show a different GB value than a storage label?
Operating systems often use binary (1,024-based) units internally while manufacturers label storage in decimal (1,000-based) units — this calculator uses the decimal convention, matching how storage capacities are marketed.
What's the difference between bits and bytes?
A byte is 8 bits. Storage sizes (files, disks) are conventionally measured in bytes, while network speeds are conventionally measured in bits per second.
How do I convert a network speed to a storage size?
Use the Data Transfer Calculator or Bandwidth Calculator instead — those directly relate a speed (bits/second) to a time and file size (bytes), which this converter alone doesn't do.
