Methodology: energy conversion factors

NiftyRecipe converts kilocalories, calories, kilojoules, megajoules, kilowatt-hours and BTU with fixed physical factors - not live market rates.

Base chain

• 1 kcal (thermochemical) = 4184 J
• 1 cal = 4.184 J (1 kcal = 1000 cal)
• 1 kJ = 1000 J, 1 MJ = 1 000 000 J
• 1 kWh = 3.6 MJ exactly
• BTU (IT) via the same joule base used in heating and AC ratings

Food labels

On packaging, “Calorie” almost always means kilocalorie (kcal). Use the kcal ↔ kJ calculator for nutrition totals.

Electrical energy

kWh → kcal is a physical equivalence, not a utility tariff or diet claim. Factors do not change by time of day.
