Real-World Energy Conversions
Electricity Bills
Understanding your power consumption in kilowatt-hours (kWh). A 100W bulb running for 10 hours uses 1 kWh. Convert kWh to joules or BTU for energy calculations.
Food and Nutrition
Converting between Calories (kcal) and joules for nutritional information. Food energy content is measured in Calories, with 1 Calorie equaling approximately 4.2 kilojoules.
Heating and Cooling
HVAC systems use BTU (British Thermal Units) to measure heating/cooling capacity. Converting BTU to watts or joules helps compare different systems.
Physics and Science
Scientific calculations use joules as the SI unit of energy. Converting between joules, kilojoules, and megajoules for physics problems and research.
Battery Capacity
Batteries are rated in watt-hours (Wh) or milliamp-hours (mAh). Converting between units helps compare battery performance and runtime.
Fuel Energy Content
Fuels are compared using energy content per unit mass or volume. Converting between joules per gram, BTU per pound, or kWh per liter.
