Where you'll actually use this

Energy converters bridge joules, calories, kilowatt-hours, BTUs, and electron-volts — the same physical quantity expressed for science, nutrition, electricity, or HVAC.

  • Electricity bills

    Usage is billed in kWh. Convert to joules for physics, or to BTU for HVAC comparisons.

  • Nutrition

    Food 'calories' are actually kilocalories (kcal). 1 kcal = 4,184 J. EU labels list both kcal and kJ.

  • HVAC & cooling

    Air conditioner output is quoted in BTU/h in the US, watts elsewhere.

Common mistakes to avoid

  • Calories vs kilocalories

    When a food label says '250 calories' it really means 250 kcal = 250,000 small calories.

  • kW vs kWh

    kW is power (rate); kWh is energy (total). A 1 kW heater running for 2 hours uses 2 kWh.

Did you know?

1 kWh runs a fridge for a day

A typical modern fridge uses about 1 kWh per 24 hours — roughly $0.10–$0.30 depending on local rates.
