What is bulk unit conversion?
Bulk unit conversion lets you convert a list of values at once instead of converting one number at a time. This is useful for data processing, spreadsheet work, and any workflow where you have many values to convert.
The "to unit" list only shows units that measure the same thing as your "from unit" — for example, choosing megabytes offers only other storage units, never centimeters.
