How this system works

Food “calories” are kilocalories (thermochemical). Electrical bills use kilowatt-hours: 1 kWh = 3.6 megajoules exactly. The international table BTU and the thermochemical calorie still coexist, so Fathom labels the IT values used in most engineering tables.

Base unit: joule. Kilojoule is Metric; Kilocalorie is Other.
