1 billion BTU = ~1.055056e12 joules
1 BTU = 1055 Joules
BTU x 1,055.056 = joules
Kilocalorie is largest. 1 kilocalorie = 1000 calories = 4,200 Joules = 3.98 BTU
1 hp for one second = 707 joules 1 hp = 746 watts 1 watt second = 1 joule of energy 1 btu = 1.055 joules So if you use 746 watts for one second you come out with 707 btu 746 watt second divided by 1.055 joules = 707 btu John L Lake Worth, Fl
One thousand cubic feet of gas (Mcf) -> 1.027 million BTU = 1.083 billion J = 301 kWh
1 BTU = 1055 Joules
1 btu = 1055.05585 joules1 joule = 0.00094781712 btu
1 BTU(ISO) = 1,054.5 Joules 1 Joule = 0.00094832 BTU(ISO) (rounded)
BTU x 1,055.056 = joules
One btu will heat a pound of water about one degree Fahrenheit in one hour.
1 cal/day*0.003968321 Btu/cal *1day/24hr = 0.003968321/24 = 0.000165347 Btu/hr
Kilocalorie is largest. 1 kilocalorie = 1000 calories = 4,200 Joules = 3.98 BTU
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!

The Joule. This is the product of Force (in Newtons) and Distance (in meters) Energy is usually measured in terms of heat, which is measured in calories or joules The SI unit of energy is the Joule. In the ft lb system it is ft.lbforce. 1 ftlbf = 1.356 joule. Thermal energy is measured in calories, 1 calorie = 4.2 Joules, it can also be in BTU, 1 BTU = 1055 Joules
One BTU is equal to one degree Fahrenheit in the sense that it one BTU is the amount of heat required to raise a pound of water's temperature by 1 Degree Fahrenheit. BTU is short for British thermal unit.
