What is a BTU?

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

1580 megajoules in BTU

1580 megajoules is 1497551.050095 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 megajoule = 947.81712 BTU, so this amount becomes 1497551.050095 BTU. Reverse: 1 BTU ≈ 0.001055 megajoule.

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.
