What is a BTU?

British thermal unit-energy needed to raise the temperature of water; common for AC and heating capacity ratings.

285 calories in BTU

285 calories is 1.130215 BTU on NiftyRecipe using a fixed thermal-energy factor.

British thermal units show up on air-conditioner nameplates, furnace ratings and heating-load notes. Converting them to kcal, kJ or kWh uses 1 calorie = 0.003966 BTU, so this amount becomes 1.130215 BTU. Reverse: 1 BTU ≈ 252.164401 calorie.

The text stays on capacity and energy equivalence-not oven temperatures or duct geometry-so these pages stay distinct from food-label converters. Adjust the amount above for different appliance ratings or textbook examples.
