Accuracy and rounding
Use energy units for accumulated work or heat. Do not confuse kWh with kW, which is power rather than energy.
Energy units share a fixed joule reference. Food Calories are kilocalories, while a small calorie is 4.1868 joules.
For billing, nutrition, or engineering, match the precision of the original kcal data and keep the energy/power distinction explicit.
