HKJ refers to the acronym for "Hektjoule." The term "Hektjoule" is derived from the combination of the prefix "hekt-" which stands for "hecto-" indicating a factor of 100, and the unit of energy "joule."
A joule is the derived SI unit of energy, named after the physicist James Prescott Joule. It is defined as the amount of energy transferred when a force of one newton is exerted over a distance of one meter in the direction of the force. The hektojoule, abbreviated as HKJ, is equal to 100 joules, making it equivalent to 10^-1 kilojoules (kJ).
The Hong Kong dollar, often abbreviated as HKD, is not associated with the acronym HKJ. Instead, it is the official currency of Hong Kong, a special administrative region of China. The currency code for the Hong Kong dollar is HKD.
