Work out btu converter instantly with clear inputs, formula shown and shareable results.
Each energy unit is defined as a multiple of the joule, so the conversion runs in two steps: multiply by the source unit's factor to reach joule, then divide by the target unit's factor. One factor per unit covers every pair in the list. This uses the International Table BTU of 1,055.05585262 J, the value standard in HVAC work.
Two-step conversion
result = value × factor(from) ÷ factor(to)
Base value
base (joule) = value × factor(from)
With 11 units, direct pairs would mean 110 factors to maintain. Going via joule needs one factor per unit and gives the same answer.
Yes. The first is the unit your figure is already in; the second is what you want it in. Swapping them inverts the result.
