## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/computer-storage-units-conversion-calculator/?value=1&fromUnit=GB&toUnit=GiB

## Inputs
- value: Storage amount; type=number; required; default=1; min=0
- fromUnit: From unit; type=select; required; default=GB; values=bit|B|KB|MB|GB|TB|KiB|MiB|GiB|TiB
- toUnit: To unit; type=select; required; default=GiB; values=bit|B|KB|MB|GB|TB|KiB|MiB|GiB|TiB

## Outputs
- result: Converted storage; format=number; primary
- bytes: Equivalent bytes; format=number

## Formula
bytes = value × bytes-per-source-unit; result = bytes ÷ bytes-per-target-unit

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
