How to Use File Size Converter
- Enter a numeric value in the input field.
- Select the source unit (Bytes, KB, MB, GB, TB, or PB).
- Toggle between binary (1024) and decimal (1000) standards.
- View all equivalent values at once in the results grid, including bit values for bandwidth context.
- Click the copy button next to any result to copy it to your clipboard.
Understanding File Size Units
File sizes are measured in bytes and their multiples. There are two competing standards: the binary standard (base 1024), used by operating systems and memory, and the decimal standard (base 1000), used by storage manufacturers and networking. This tool converts between all common units in both standards and also shows bit-based values, which are essential for understanding network bandwidth and data transfer rates.
