BTU vs kcal?

Both measure energy. Roughly 1 kcal ≈ 3.97 BTU (IT). Use the exact factor on this page.

Manual conversion?

BTU = kcal × 3.965667 (1 KCAL = 3.965667 BTU)

Reverse?

1 BTU ≈ 0.252164 kilocalorie.

777 kilocalories in BTU

777 kilocalories is 3081.323128 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 kilocalorie = 3.965667 BTU, so this amount becomes 3081.323128 BTU. Reverse: 1 BTU ≈ 0.252164 kilocalorie.

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.
