Kilowatts (kW) and British Thermal Units (BTU) are both units of measurement used to quantify energy and power. However, they represent different aspects of energy:
Kilowatts (kW)
- Kilowatt is a unit of power in the International System of Units (SI). It measures the rate at which energy is transferred or work is done.
- 1 kilowatt is equal to 1,000 watts. It represents the power required to perform 1,000 joules of work in one second.
- Kilowatts are commonly used to describe the power output of electrical devices, machines, and engines.
British Thermal Units (BTU)
- The British Thermal Unit is a unit of energy traditionally used in the United States and other countries following the Imperial system of measurements.
- 1 BTU is approximately equal to the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.
- BTUs are often used to measure the heating and cooling capacities of appliances like air conditioners, furnaces, and heaters.
How to convert kW to BTU
To convert kilowatts (kW) to British Thermal Units (BTU), you can use the following conversion factor:
1 kilowatt (kW) =- 3,412 BTUs.
So, to convert from kilowatts to BTUs:
P(BTU) = 3412.142 ⋅ P(kW)
For example – Convert 18 kw to btu/hr
Ans. P(BTU/hr) = 3412.142 ⋅ 18kW = 61418.556 BTU/hr

FAQs on Kilowatts to BTU conversion
How many kW is a BTU?
One British Thermal Unit (BTU) is approximately equal to 0.000293 kilowatts (kW).
How many kilowatts is 12,000 BTU?
To convert BTU to kilowatts, divide the number of BTUs by 3,412 (since 1 kW is approximately equal to 3,412 BTUs). Mathematically: 12,000 BTU ÷ 3,412 ≈ 3.52 kW
How many BTU is 1 kWh of electricity?
One kilowatt-hour (kWh) of electricity is equal to approximately 3,412 BTUs.
How many kW is 1.5 ton AC?
To convert tons of cooling capacity to kilowatts, multiply the tons by 3.516. Mathematically: 1.5 tons × 3.516 ≈ 5.274 kW
How many AC can run in 1 kW?
The number of air conditioners that can run on 1 kilowatt depends on the cooling capacity of each individual air conditioner. If each AC has a cooling capacity of 1.5 tons (5.274 kW), then: 1 kW ÷ 5.274 kW ≈ 0.19 AC So, approximately 0.19 (or about 1/5) of an air conditioner with a cooling capacity of 1.5 tons can run on 1 kilowatt of power. In practical terms, you would likely need at least 1 kilowatt for one 1.5-ton AC to run properly.
