File sizes in megabytes, storage plans in gigabytes, download sizes in kilobytes — data storage units come up constantly, and the difference between binary (1024-based) and decimal (1000-based) definitions can cause real confusion.
This tool converts between six common data storage units — bits, bytes, kilobytes, megabytes, gigabytes, and terabytes — using the binary (1024) convention that operating systems and file managers typically use.
How it works
Enter a value, choose the unit you're converting from and the unit you want to convert to. The tool handles any combination of the six supported units using the 1024-based binary convention.
- Enter value.
- Enter from.
- Enter to.
- Click Calculate to see your results.
Examples
Converting a file size
1 gigabyte converts to 1,024 megabytes — the same convention your operating system uses when reporting file and disk sizes.
Who should use it
- Converting file sizes between megabytes and gigabytes.
- Estimating how many files of a given size fit on a storage device.
Industry applications
- IT and system administration
- Software development
Advantages
- Supports the full common range from bits to terabytes.
- Uses the same binary convention operating systems use.
Limitations
- Doesn't offer a decimal (1000-based) mode for comparing against manufacturer-advertised capacities.
Common mistakes to avoid
- Assuming a storage manufacturer's advertised capacity (often decimal/1000-based) will match exactly what your OS reports (binary/1024-based).
Best practices
- When comparing a purchased drive's advertised size to what your OS shows, remember the two commonly use different conventions.
Tips
- If a number looks off compared to a manufacturer's spec sheet, check whether they're using the 1000-based decimal convention instead of 1024-based binary.
