In at least as early as the 15th century – 19th century, a unit of mass for coal, which was originally limited by the size of the boats carrying the coal downriver to the harbor. The size of the boats was in turn limited, in part, by the need to pass under a certain bridge. See chaldron.

Raithby, Statutes of the Realm, vol 5, page (1819)
To improve readability, the paragraphing and punctuation and the spelling of place names have been slightly modernized.
Section I defines the boll as 22½ gallons and the chaldron as 21 such bolls, heaped measure, or 472.5+ gallons, or about 59 Winchester bushels. Notice the score of 21.
Section II defines the wain as 7 bolls and the cart as 3½ bolls, heaped measure, and the chaldron as 6 carts or 3 wains.
The significant omission is the size of the keel itself, probably because in practice the keel was now 8 chaldrons, which could not be reconciled with Henry V's 20-chaldron keel.

And bee it further enacted by the authority aforesaid That in case after the marking and nailing of any Keel Boat Wain or Cart the mark shall bee removed or altered whereby to frustrate the intent and meaning of this Act that every person and persons that shall have a hand in or bee privy to the doeing thereof and shall upon proof thereof by one or more credible witnesses before any one or more Justice or Justices of the Peace of the Counties where the said offence shall happen to bee com[m]itted & convicted thereof such person or persons soe as aforesaid convicted shall forfeit the su[m]m of Ten pounds to bee levied upon his or their Goods and Chattels by distress and sale thereof by warrant under the hand and seale of the said Justice or Justices rendring the overplus (if any) to the partie or parties distrained upon and for want of sufficient distresse the parties soe offending shall by like warrant bee committed to the common Gaol of the said County where the offence shall bee committed there to remaine for the space of Three months without bail or mainprize one halfe part of the said forfeiture to his Majestie his heires and successors and the other halfe part thereof to such person or persons as shall make such discovery and alsoe that after any such offence as aforesaid committed by altering or removing any of the marks or nails that shall bee sett upon any such Keels Boats Wains or Carts by virtue of this Act that from thenceforth and soe. often as any such offence shall bee comitted as aforesaid the said Commissioners or any Three of them or such person or persons as shall bee by them appointed shall have authority and are hereby authorized and impowered to admeasure mark and nail the said Keels Boats Wains and Carts anew according to the directions hereby before given.
Notice the inconsistency in the definition of the chaldron: first as 53 hundredweights, but 3 wains at 17½ hundredweights each is 52½ hundredweights. In practice the 53 cwt value was the accepted weight.
A keel of coals is 21 ton 4 cwt. and contains 8 Newcastle chaldrons, so that each chaldron is 53 cwt. — A London chaldron contains 36 heaped Winchester bushels, and weighs on an average near 28½ cwt. (according to the quality of the coals) which weights being nearly in the ratio of 8 to 15, it is always reckoned, that 8 Newcastle chaldrons make 15 London chaldrons.

1863, July 6. The following document was signed and issued by a majority of the leading mercantile firms of Newcastle :- "We, the undersigned merchants, shipbrokers, and shipowners of Newcastle-upon-Tyne, recognising that the keel has long been obsolete, and does not now in reality exist as a standard measure, that it bears no relation to foreign weights and measures, but one that is most difficult and tedious to establish (the reduction having first to be made in tons and cwts., and subsequently into keels); and furthermore that coal and coke are now sold by the ton, and not by keels and chaldrons, hereby pledge ourselves and agree to commence at an early date, to conduct all our chartering operations, whenever and wherever practicable, on the basis of the established and legitimate weight of the realm, viz., the ton, in order to simplify calculations, which as hitherto conducted, cannot have failed to be a source of great inconvenience to foreigners having business with this port."*
* Other measures and denominations used in the Coal-trade, as the peck, boll, and ten, could advantageously be done away with or simplified.
