Chaldron

Chaldron (also Chaudron or Chalder ) was originally a British unit of measurement of pourable solids either as a volume or as a measure of weight, but later only for coal usual ( since 1826). The use of the unit ended in 1963 with the reform of the Weights and Measures Act.

Depending on the area a Chaldron was specified differently:

• The London Chaldron was 24 Hundred Weights ( English hundredweight ) or 2,688 English trade pounds ( = 1219.25 kg ).
• The Newcastle Chaldron measured 53 Hundred Weights or 5,936 pounds = 2692.5 kg.
• Especially for coal was 1 Chaldron = 36 bushels, which ( avoirdupois ) (= about 256 kg) corresponded to a weight of 566 pounds.

At purchase of 5 Chaldron (60 bag) coals had the seller 3 bag admit a so-called Hafenmaß in engl. Ingrain.

In Newcastle were with coal

• 8 Chadron = 1 Keel

The Chaldron in Newcastle differed from London and was twice as large.
