BTU and kilojoules are units of energy commonly used in different parts of the world.
BTU (British Thermal Unit)
BTU is a unit of energy commonly used in the United States and some other countries, especially in relation to heating and cooling systems. It is defined as the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit. The exact value of a BTU can vary slightly depending on the reference conditions used, but it’s approximately equal to 1055.05585 joules.
Kilojoule (kJ)
The kilojoule is a metric unit of energy. It’s defined as 1000 joules. Joule is the SI unit of energy, and it’s defined as the amount of energy transferred when a force of one newton acts on an object over a distance of one meter. The kilojoule is commonly used in scientific and nutritional contexts, and it’s often used to measure the energy content of food.
How to convert BTU to Kilojoules
1 BTUIT = 1.05505585262 kJ
So,
E(kJ) = 1.05505585262 ⋅ E(BTU)
For example: Convert 5 BTU to KJ
Ans. E(kJ) = 1.05505585262 ⋅ 0.5 BTU = 0.527528 kJ

FAQs on BTU to Kilojoules conversion
What is BTU in kJ/kg?
BTU (British Thermal Unit) is approximately equal to 1055.06 joules. So, to convert BTU to kilojoules per kilogram (kJ/kg), divide the BTU value by 0.2388459.
Is a kJ the same as a BTU?
No, a kilojoule (kJ) and a BTU (British Thermal Unit) are not the same. While they both measure energy, 1 BTU is roughly equal to 1.05506 kJ. They are used in different regions and applications.
How do I convert BTU into kW?
To convert BTU to kilowatts (kW), divide the BTU value by 3412.142. This conversion takes into account the time factor since kilowatts represent energy per unit time.
What is BTU in kJ/kg?
BTU in kJ/kg refers to the energy content of a substance in kilojoules per kilogram. It can be calculated by dividing the BTU value by 0.2388459.
How do I convert BTU into kJ?
To convert BTU to kilojoules (kJ), multiply the BTU value by approximately 1.05506.
Is a kJ the same as a BTU?
No, a kilojoule (kJ) is not the same as a BTU (British Thermal Unit). While they both measure energy, 1 BTU is roughly equal to 1.05506 kJ.
What is the BTU formula?
The formula for calculating BTU can be given as: BTU = (Mass in pounds) × (Temperature difference in Fahrenheit) × 0.2388459
What is BTU value?
The BTU value represents the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. It is commonly used in heating and cooling systems to quantify energy transfer.
