Tips & common mistakes

Quick tips

1 BTU/h = 0.293 W; 3412 BTU/h = 1 kW.
12,000 BTU/h = 1 ton of refrigeration.
Tons of AC rating: divide BTU/h by 12,000.

Avoid these

Confusing BTU (energy) with BTU/h (power) — same abbreviation in ads.
Mixing tons of AC and tons of weight — different concepts.
Using BTU/h for non-HVAC contexts.
