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.

How many watts is 13500 BTU?
You can't convert that.* A BTU is a unit of energy. * A watt is a unit of power (energy per unit time).
What is the equation for converting btus to kilowatt-hour?
BTUs and kilowatts measure different types of quantities. A BTU (British Thermal Unit) measures heat (energy), while a kilowatt (1000 watts) measures power (energy per unit time). 1 BTU equals 0.0002928 kilowatt-hour 1 BTU/minute equals 0.01757 kilowatt. To convert a watt to BTUs, the factor is 1 kilowatt of power = 3412.1416 BTU/hr 3.412 BTUs equal a watt-hour. 1 kW = 3412.1416 BTU/hour with appropriate significant figures 3*103 BUT per hour
How much btu equals 1 watts?
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.
How do you convert Foot-pounds per minute to British thermal units per hour..HELP?
Use this formula: foot-pounds per minute x0.0771 = BTU per hour
How many amps 2300 btu 240 volts?
Assuming we are talking about 2300 BTU per hour, take 2300 and divide by the number of BTUs per watt-hour, 3.414, giving 673 watts. Then divide this by the voltage, 240, giving 2.81 amps.
Are BTU ratings calculated in btu's per hour?
Yes, usually. 100 watts equates to about 341.21 BTU per hour.
How many watts per hour to equal 1000 btu's?
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.

How do you calculate BTU heat gain based upon electric watts?
1 Watt = 3.412141633 BTU/hour, so multiply the number of watts (that are converted to heat) by the factor, to get BTU per hour. Multiply this by the number of hours that it is running, to find BTUs.
How many BTU's per hour is in 1 ton of refrigeration?
1 ton = rate of heat absorption to melt 1 ton of ice in 24 hours =12,000 BTU per hour = 3,516 watts.
Converting volt amps into btu?
This is a two-step question. First, to convert volt-amps into watts, multiply by the power factor. For a heating element like a convector or kettle the power factor is 1, but for a motor it might be 0.7. In the absence of information a power factor of 0.8 can be assumed. Watts are a measure of power and the equivalent imperial measure is BTU per second or BTU per hour. Alternatively a BTU is a measure of energy and the metric equivalent is watt-seconds or watt-hours. A BTU is 1055 watt-seconds (also known as joules). A kilowatt-hour is equivalent to 3412 BTU.
