Formula and assumptions
J/TH = power in watts ÷ hashrate in TH/s. A watt is one joule per second.
Measure watts and TH/s at the same operating point. Firmware and temperature affect both; nominal manufacturer J/TH can be rounded.

ASIC efficiency calculator
Calculate joules per terahash from wall power and hashrate. Lower values mean less energy per hash.

Worked example
3,500 W ÷ 200 TH/s = 17.5 J/TH. Zero hashrate has no defined efficiency.
Arithmetic examples explain the tool; they are not live market observations. Reference specifications are linked on ASIC pages.

Does lower J/TH imply higher returns?
It uses less energy per hash; purchase prices and running conditions still matter.
Can I compare different algorithms?
No. Equal units across algorithms do not represent equivalent mining work.
