AI explanation
Formula
Converted value = amount × (from-unit-to-bytes factor) ÷ (to-unit-to-bytes factor)Worked example
1 GB to MB
| Field | Value |
|---|---|
| Amount | 1 |
| From unit | gb |
| To unit | mb |
| Converted value | 1024 |
Assumptions
- Uses the binary (1024-based) convention common in operating systems and file managers — 1 KB = 1024 bytes, not the SI decimal (1000-based) convention some standards bodies define. A file labeled "1 GB" by your OS matches this calculator's convention.
Frequently asked questions
Why does 1 GB equal 1024 MB here, not 1000?
This calculator uses the binary convention (powers of 1024) that Windows, macOS, and most file managers use to report file and storage sizes — some manufacturers and standards bodies instead use a decimal (1000-based) convention, which is why a "1 TB" hard drive can show up as slightly less than 1 TB in your operating system.
How many bytes are in a bit?
1 byte = 8 bits, so 1 bit = 0.125 bytes.
What data size units does this support?
Bits, bytes, kilobytes, megabytes, gigabytes, and terabytes.
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 binary convention, so its results match what your operating system shows rather than the number on the label.
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.
