200 BTU = 211,000 joules.
There are approximately 0.00094781712 BTU in one joule.
1 btu = 1055.05585 joules1 joule = 0.00094781712 btu
1 BTU(ISO) = 1,054.5 Joules 1 Joule = 0.00094832 BTU(ISO) (rounded)
BTU/calorie/joule .
One btu will heat a pound of water about one degree Fahrenheit in one hour.
The amount of BTU's per square foot varies. The BTU's per ft2 in my area is 30-35. In your area there might be more or less. For reference sake... Btu's are not used in Metric settings, Joules are used. 1 btu = 11356 joule Contact a HVAC tech in your area. They can tell you the recommended BTU or JOULE rating for your area with the use of a manual known as a "J manual" +++ To be proper, BTU should be all capitals as in the first sentence, though correct abbreviations are very awkward to use in many Microsoft applications!
1 billion BTU = ~1.055056e12 joules
To convert joules to British thermal units (Btu), you can use the conversion factor: 1 joule is equal to 0.000947817 Btu. Therefore, 57281 joules is equivalent to 57.81 Btu.
Kilocalorie is largest. 1 kilocalorie = 1000 calories = 4,200 Joules = 3.98 BTU
Joule, calorie, BTU (British Thermal Unit)
1 BTU (British Thermal Unit) is approximately equal to 1055.06 Joules.
This is a measure of power. Power is the rate of use or production of energy. Usually it is defined as the amount of energy per second. Thus if energy is measured in Joules, then a rate of 1 Joule per second is a power of 1 watt. If you are thinking of thermal energy, this will be in calories or BTU. There is no specific unit for calories/sec or BTU/sec, but they can be related to watts. 1 calorie/sec = 4.2 watts, 1 BTU/sec = 1.055 Kw
