📐 How BTU and Kilowatt-hour (kWh) Relate
In metrology, energy quantifies capacity to perform mechanical work or transfer heat ($M \cdot L^2 / T^2$). Within this domain, BTU and Kilowatt-hour (kWh) 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 BTU and Kilowatt-hour belong to the linear energy domain, conversion between them is strictly proportional. The exact conversion factor (0.00029307) guarantees zero precision drift across mathematical calculations.
