btu/h watts formula
The BTU per Hour to Watts Calculator is used to convert between BTU/h (British Thermal Units per hour) and watts (W), two of the more common power units in heating, ventilation, and air conditioning (HVAC) and electrical and thermal engineering. the change is as follows: 1 Btu/ h = 0.29307107 W and vice versa 1 W = 3.412141633 Btu/h. This is necessary in cases calling for comparison of the U.S. customary HVAC capacity rating to SI-related electrical or mechanical power ratings. Engineers, technicians and homeowners find it handy to verify the heater or air conditioner specs, estimating power requirement or air conditioner efficiency. The equation is easy to solve, the figures accurate and the calculator fine-tuned to produce precise or correct answers without having to go manual computing.

Frequently Asked Questions - Btu per hour to watts calculator:
What is the BTU/h to watts formula?
W = BTU/h × 0.29307107.
How do I convert watts to BTU/h?
BTU/h = W × 3.412141633.
Why is 1 W equal to 3.412 BTU/h?
It comes from the definition of the BTU and conversion from joules per second.
Is this used for HVAC?
Yes, HVAC systems often list capacity in BTU/h which can be converted to watts.
Does this apply to cooling and heating?
Yes, the formula is the same for both cooling and heating capacity.
What is a BTU?
A BTU is the amount of heat required to raise 1 lb of water by 1°F.
Why use watts instead of BTU/h?
Watts are the SI unit of power and used globally in electrical and mechanical engineering.
How do I convert BTU/h to kW?
kW = (BTU/h × 0.29307107) ÷ 1000.
