Binary vs decimal: why your drive looks smaller
Windows and RAM reports count in powers of 1,024 (binary, sometimes written KiB/MiB/GiB); drive makers, macOS and mobile carriers count in powers of 1,000 (decimal). Same bytes, two answers:
| Megabytes | Gigabytes (binary · Windows) | Gigabytes (decimal · on the box) |
|---|---|---|
| 1 MB | 0.000976562 GB | 0.001 GB |
| 2 MB | 0.00195312 GB | 0.002 GB |
| 4 MB | 0.00390625 GB | 0.004 GB |
| 5 MB | 0.00488281 GB | 0.005 GB |
| 8 MB | 0.0078125 GB | 0.008 GB |
| 10 MB | 0.00976562 GB | 0.01 GB |
| 16 MB | 0.015625 GB | 0.016 GB |
| 20 MB | 0.0195312 GB | 0.02 GB |
| 32 MB | 0.03125 GB | 0.032 GB |
| 50 MB | 0.0488281 GB | 0.05 GB |
Example: a “1 TB” drive holds 10¹² bytes, which Windows shows as about 931 GB.
Real-world data storage in megabytes and gigabytes

The units
Here, 1,024 KB = 1,048,576 bytes (MiB). Decimal megabyte = 1,000,000 bytes.
Used for: Photos, songs, app downloads.
Here, 1,024 MB = 1,073,741,824 bytes (GiB). Decimal gigabyte = 1,000,000,000 bytes.
Used for: Phone storage, mobile data, RAM.
This page uses binary units (1 KB = 1,024 bytes), which is how Windows and most RAM reports count. Storage makers and macOS use decimal units (1 kB = 1,000 bytes), so both are shown below.
