There are two ways to do this.
- Rough estimate If you know. One kilowatt is equal to 1000 watts so to calculate how many kWh a device uses divide the watt-hours from the previous step by 1000. Mining metrics are calculated based on a network hash rate of 784654 GHs and using a ETH - USD exchange rate of 1 ETH 418411. This will also show you how to calculate how much a specific device costs to use.
