Convert from keel [coal] to tical [Asia]

Unit Definition (keel [coal])
The keel is a traditional British unit of weight for coal. After considerable variation, the keel of coal was standardized in 1695 as 21.2 long tons, or 47 488 pounds (21.5402 metric tons). This is the approximate weight of coal carried at that time by barges on the river Tyne in northern England; the barges were also called keels, from the Dutch word kiel for such a ship.

Unit Definition (tical [Asia])
The tical is a traditional unit of weight in southeast Asia, originating as the weight of a coin of the same name. In Myanmar (Burma), where the unit is still in use for measuring the weights of precious metals and drugs, the tical is equivalent to 16.4 grams.
