This short YouTube instructional segment (speaker: Derek Cole) explains core HVAC and electrical power calculations: the thermal formula CFM × ΔT × 1.08 = BTUs, the conversion factor 3415 BTU per kW for comparing thermal and electrical units, and basic electrical relations (Watts = Amps × Volts; kW = Watts ÷ 1000). The speaker frames these as practical steps for measuring and converting power when working with HVAC and electrical systems.

Questions this video answers

CFM × ΔT × 1.08 = BTUs.

3415 BTU per kW.

Watts = Amps × Volts.

kW = Watts ÷ 1000.

All right, so this is CFM times Delta T times 1.08 equals BTUs. Now I remember. All right, that's how all this comes. This is how all this comes about. All right, the only thing that's different than electric is there is 3415 BTUs per kilowatts. How do we find out? KW? Just look. No, we're gonna actually measure KW equals amps. Amps times volts. Yes. That equals. Actually, that's watts. Amps times volts divided by a thousand is kw.
