1 watt/m2= btuhr/ft2.f
The conversion is not direct, since watts are units of power, while BTU/Hr represents energy per hour of equipment operation. So, in this case, watts will represent the power dissipation of a product. 1 watt = 3.412141633 BTU/Hr It works both ways, of course: 1 BTU/Hr = 0.29307107 watts The above is mathematically correct, but I think how it represents the time value is confusing. I've left it for reference purposes. A Watt is an instantaneous measure of power. It assumes no unit of time. A Watt-Second on the other hand, is 1 Watt of power for 1 Second, which *is* a unit of energy. 1 Watt-Second is equivalent to 1 Joule. A 60 watt lightbulb turned on for exactly 1 second uses 60 Watt-seconds or 60 joules of energy. BTU on the other hand, is a measure of energy and time is implicit in the unit. 1 BTU is equivalent to approx 1055 Joules. 1 Watt-Second = ~0.00095 BTU. A 1000 Watt heater, running for 1 hour(3600 seconds) would consume 1KiloWatt-Hour(KWH) of energy. Or 3,600,000 Joules. 1KiloWatt-Hour = 3412 BTU. OR 1Watt-Hour = 3.412 BTU While you could divide both sides by Hours and get a comparison of power wherein 1W = 3.412 BTU/hr. I think comparing energy in the forms of KWHs and BTUs is more useful than the other way around.
Since 1KW-H (kilowatt-hour) = 1000 Watt-Hours =3413 BTU Then 1 watt-Hr = 3413 BTU divided by 1000 = 3.413 BTU So... bottom line is 1 watt-hour is equal to 3.413 BTU Note: For Reference: 1 BTU is the amount of energy required to raise (or lower) 1 (one) pound of water 1 (one) degree Fahrenheit.
8000 BTU =2344.66 watts 1 watt = 3.412
An 8000 watt generator at regular house current 110v will supply 72 amps.
1500 watts is equivalent to 5118 BTU per hour. 1500 watt-hours is equivalent to 5118 BTU.
btu = 7500 watts * 3.14 btu / watt = 23,550 btus / hr
4000 BTU = 1722 watts
One ton of cooling is about 12,000 Btu/h one Btu/h is 0.293 watt so...One ton = 3.516 Kilowatts
400 watt hours = 1,364.86 BTU
To convert a watt to BTUs, the factor is 1 kilowatt of power = 3412.1416 BTU/hr 3.412 BTUs equal a watt. 1200 watt = 4094.4 BTUS you will need to remove about 4100 BTU/hr
The BTU is an Imperial unit of measurement for energy. The watt is the SI unit for power. The BTU and watt measures different quantities, so there are no 'BTUs per kilowatt'!
Does not computeKilowatts do not convert to BTU and vice versa. The watt is a unit of power, whereas the BTU is a unit of energy. Perhaps you meant BTU/hr. 1.5E5 BTU/hr = 43.96 kilowattsYou could do a direct conversion into Killowatt hours though one would assume.1.5E5 BTU = 43.96 KWh
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

About 90 percent of an incandescent bulb's energy is turned into heat; one watt is 3.41 btu/hr, so 10 watts would be about 3 btu per hour.
