1BTU= 1.05505585 joules
It is approximately the amount of energy needed to heat 1
pound (0.454 kg) of water 1 °F (0.556 °C). It is used in
the power, steam generation, heating and air conditioning
industries. In scientific contexts the BTU has largely been
replaced by the SI unit of energy, the joule, though it may
be used as a measure of agricultural energy production
(BTU/kg). It is still used unofficially in metric English-
speaking countries (such as Canada), and remains the
standard unit of classification for air conditioning units
manufactured and sold in many non-English-speaking metric
countries.
In North America, the term "BTU" is used to describe the
heat value (energy content) of fuels, and also to describe
the power of heating and cooling systems, such as furnaces,
stoves, barbecue grills, and air conditioners. When used as
a unit of power, BTU per hour (BTU/h) is the correct unit,
though this is often abbreviated to just "BTU".
The unit MBTU was defined as one thousand BTU, presumably
from the Roman numeral system where "M" stands for one
thousand (1,000). This is easily confused with the SI mega
(M) prefix, which multiplies by a factor of one million
(1,000,000). To avoid confusion many companies and
engineers use MMBTU to represent one million BTU.
Alternatively a therm is used representing 100,000 or 105
BTU, and a quad as 1015 BTU.

Answer / vikrant yadav
In the English system, the energy unit is the Btu (British thermal unit), which is defined as the energy required to raise the temperature of 1 lbm of water at 68°F by 1°F.The magnitudes of the kilojoule and Btu are almost
identical (1 Btu =1.0551 kJ).
