Energy

Four small instruments for the units that decide what a machine costs to run. All values are examples you can overwrite.

Instrument 01

Efficiency converter

Illustrative The starting value is an example, not a rating of any machine.

A positive number in the unit you choose.

Pick the unit your number is written in.

Why J/TH and W per TH/s agree. A watt is a joule per second, so a machine that spends 20 joules per terahash while doing one terahash per second draws 20 watts for each TH/s. The two figures are numerically identical. Only the way you read them differs: one is energy per unit of work, the other is power per unit of speed.

UnitValue
Enter a value to convert.

Where that sits on a logarithmic J/TH scale (lower is better)

Scale runs from 1 to 200 J/TH. Readings outside that range pin to the nearest end.

Instrument 02

Machine sheet

Three quantities are linked by one equation: power = efficiency × hashrate. Fill two, solve the third.

Solve for

Terahashes per second.

Watts drawn.

Same number as W per TH/s.

Instrument 03

Kilowatt-hour costing

Turn a power draw, a running time and a tariff into energy and money, and into heat.

Continuous watts.

Between 0 and 24.

Illustrative example. Use your own.

PeriodEnergy (kWh)Cost (USD)
Enter valid values to cost the load.

Instrument 04

Hashrate scale

Machines are quoted in TH/s, networks in EH/s. Each step up is a factor of one thousand.

Zero or more.

Unit of the value.

Assumptions and edge cases

All conversions are exact unit arithmetic. One joule per terahash is one picojoule per hash, one thousand joules per petahash, one thousandth of a joule per gigahash, and one kilowatt for each petahash per second. Nothing is estimated.

  • Costing multiplies power in kilowatts by hours and by your tariff. A month is taken as 30 days and a year as 365; real bills depend on your billing cycle, tiers and demand charges.
  • Heat output equals power input for practical purposes. One watt is about 3.412 BTU per hour; the figure shown uses that factor.
  • Machine sheet needs two positive quantities. Solving for the third replaces its field with the result and marks it read-only until you choose another unknown.
  • Zero, blank, negative and non-numeric entries produce a plain message beside the field and leave the other results unchanged. Entries too large to be meaningful are refused rather than shown in scientific notation.
  • Efficiency figures describe a machine at a moment. Voltage, temperature and tuning change them, and a wall meter reading always beats a datasheet.
