Copy-paste (or type) dimensions of an object into one box and it will be converted to the opposite units on the other side.
Conversion process is relatively garbage-tolerant, so it can be useful for copy-pasting from various sources and getting standardized output.
Conversion output will always be sorted into order of LxWxH, where L>=W>=H.
If you commonly use an input format that is not recognized or parsed correctly, please let me know:

Imperial (inches)

Metric (millimetres)

Imperial (pounds)

Metric (kilograms)
