01
Fixed factors
1 kW equals 3,412.14 BTU/h and 859.85 kcal/h.
02
Why BTU?
AC units and refrigeration are often rated in BTU/h — this places them in kW.
03
Rough cooling load
For rough sizing, count ~60–100 W of cooling load per m² depending on the situation.
Pure unit conversion; does not replace a cooling- or heating-load calculation for the specific case.
