The number of btus you start with (the value you enter above)
value_in_megajoule
The equivalent number of megajoules (the result)
factor
The exact conversion ratio — 0.00105506 — anchored to SI definitions, not rounded
§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 btus to megajoules.

  1. 01Look up the SI factors: 1 btu = 1055.05585 base units, 1 megajoule = 1000000 base units.
  2. 02Divide to get the conversion ratio: 1055.05585 / 1000000 = 0.00105506.
  3. 03Multiply by the quantity: 5 × 0.00105506 = 0.00527528.
  4. 04So 5 btus = 0.00527528 megajoules.
