Data Size Converter | How to use and interpret results
Expand a byte quantity into several sizes from bytes through TB. Switching the factor between 1000 and 1024 makes capacity-label differences visible without changing the underlying data.

How to use this tool
Choose the source value and unit, then select the conversion base. Include that base when sharing a result because the displayed MB label alone does not identify it.
Results and examples
At base 1000, 1 MB is 1,000,000 bytes; at base 1024 it is 1,048,576 bytes. The difference comes from the unit convention rather than missing data.
Worked example
At base 1000, 1 MB is 1,000,000 bytes; at base 1024 it is 1,048,576 bytes. The difference comes from the unit convention rather than missing data.
Limitations
- KB and MB labels require the accompanying base selection to be interpreted correctly.
- Compression and download duration are not modelled.
