Calculator uses MicroBT Whatsminer M63S Hydro 390T miner with default inputs. Provides hourly and daily mining rewards based on hashrate and power consumption. Calculates daily mining profit of $11.93 at current Bitcoin price
BMR is energy expenditure by endothermic animals at rest. Requires strict criteria including undisturbed state and thermally neutral environment. Can be measured through direct or indirect calorimetry
Ferroalloys are iron alloys containing high proportions of manganese, aluminum, or silicon. World production reached 52.8 million tonnes in 2015. Leading producers include China, South Africa, India, Russia, and Kazakhstan. Produced through blast furnaces or electric arc furnaces
Most household appliances have wattage labels on back or bottom. Look for "W" or "A" measurements instead of watts. Multiply wattage by daily usage hours to get watt-hours. Divide watt-hours by 1,000 to get kilowatt-hours
BMR is energy needed for basic body functions at rest. Exact BMR measurement requires lab-based indirect calorimetry. Mifflin St. Jeor equation provides closer BMR estimate than Harris-Benedict. Equation uses weight, height, age, and gender for calculation
United States and China lead in total energy consumption. China consumes most electricity, US most oil. Population is most influential factor in energy consumption
