📐 How Kilowatt-hour (kWh) and BTU Relate
In metrology, energy quantifies capacity to perform mechanical work or transfer heat ($M \cdot L^2 / T^2$). Within this domain, Kilowatt-hour (kWh) and BTU originate from SI joules, nutritional/thermal calories, electrical kilowatt-hours, and British Thermal Units (BTU). Standardized under ISO 80000-5 and International Steam Table thermochemical definitions.
Because both Kilowatt-hour and BTU belong to the linear energy domain, conversion between them is strictly proportional. The exact conversion factor (3412.1282202) guarantees zero precision drift across mathematical calculations.
