What is a BTU?

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

BTU vs kcal?

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

Manual conversion?

MJ = BTU × 0.001055 (1 BTU = 0.001055 MJ)

Reverse?

1 megajoule ≈ 947.81712 BTU.

How much is 438 BTUs in megajoule?

438 BTUs in megajoule

438 BTUs is 0.462114 megajoule 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 BTU = 0.001055 megajoule, so this amount becomes 0.462114 megajoule. Reverse: 1 megajoule ≈ 947.81712 BTU.

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.
