What is Data Storage Converter?
A data storage converter translates a digital storage size between bytes, kilobytes, megabytes, gigabytes, and terabytes. It's essential when your phone shows "58.2 GB used" but an app reports file sizes in MB, when comparing a mobile data plan's 1.5 GB/day quota against a downloaded file listed in KB, or when a developer needs to convert a database size from bytes into a human-readable GB figure for a report. Because storage manufacturers and operating systems don't always agree on how a "kilobyte" is defined, this tool's results follow a specific, consistent standard explained below.
Conversion Formula
This calculator uses the binary (1024-based) standard — the same one your computer's file explorer uses — not the decimal 1000-based standard some marketing materials use:
Result = value in bytes ÷ (target unit factor)
Common Conversion Factors
| Unit | Equal to (bytes) |
|---|---|
| Byte (B) | 1 B (base unit) |
| Kilobyte (KB) | 1,024 B |
| Megabyte (MB) | 1,048,576 B |
| Gigabyte (GB) | 1,073,741,824 B |
| Terabyte (TB) | 1,099,511,627,776 B |
Worked Example
How many MB is a 2.5 GB video file?
2,684,354,560 B ÷ 1,048,576 = 2,560 MB
So a 2.5 GB file equals exactly 2,560 MB under the binary standard — notice it's not a round 2,500, which is the most common confusion point with storage math.
