About these converters
Unit conversion is the kind of task that is trivial until it is not โ recipes in ounces, running distances in kilometres, server quotas in gibibytes rather than gigabytes.
Each converter uses a single documented base unit internally, so a value converted from A to B and back returns the number you started with. Where a distinction is commonly fudged, such as the difference between a megabyte and a mebibyte, both are offered separately.
