    1 btu of cooling equals?

    1 btu of cooling equals or is equifilant to?


    1 btu of heating = 1 burning match


    there are 12,000 btu's in 1 ton or 2,000 lbs of ice    this is the right path but i can not figure it out

    One Btu is approximately:
    1.054 to 1.060 kJ (kilojoules)
    0.293071 W·h (watt hours)
    252 to 253 cal (calories, or "little calories")
    0.25 kcal (kilocalories, "large calories," or "food calories")
    25 031 to 25 160 ft·pdl (foot-poundal)
    778 to 782 ft·lbf (foot-pounds-force)

    Here's that link again...if it doesn't help, I'm really sorry...

    BTU is British thermal Unit. the definition is how much heat needed to raise 1Lb of water 1 Degrees F. i am trying find the answer to what 1 btu of cooling is equal to.
    bubbadozer

    thank you but im looking for 1 btu of cooling what it is equal to

    Hi...can't find exactly what you're looking for...did you try any of the pages in this search?

    I'm posting it above in my initial answer to you.
    bubbadozer

    yes i tried the wikipedia link but that did not help and the google one will not open. my delima is i am a student going to school to get my HVAC/MAR cert and this is a question i have been trying to find out.

    Ok, thanks for your patience. Sometimes people are quite rude when we can't help them right off the bat.
    We are volunteers here at this site.
    Ok, tell me if this is of any help.

    yes that was almost spot on but not quite the answer that i need that was very close though and i appreciate you helping me thank you.
    Dardaigh

    I'm no good at math but don't/can't you divide the 12,000 into the 2,000 or vice versa for an answer or is that way off base?
    bubbadozer

    see even im not 100% sure. i know there are 12,00o btus in a 1 ton Air conditioning unit. but today in class i was asked if i knew what 1 btu of cooling equals. and turns out nobody knew. so its 100 points extra credit if i bring in a legit answer. and i can definatley use them lol. i do know for heating though that 1 match burning is equivilant too 1 btu but thats for heat. i dont know if the answer im looking for is how much does the average ice cube weigh or what but im stuck.
    Dardaigh

    This is from Wiki...

    This conversion is very simple : and is 1 ton = 12,000 BTU/hour.
    So if you have a 3 ton of refrigeration you have 36,000 BTU/hour.
    In addition, I want to add that in some large Data Centers, there is a movement from BTU to kW of power used by equipment. This is probably driving the Tons/kW question that the HVAC engineers are telling people cannot be solved.
    1 Ton of cooling will eliminate 12,000 BTU/hr of heat.
    12,000 BTU/hr will be produced by 3.516 kW of power used by equipment.
    1 Ton of cooling will then handle 3.516 kW of equipment load based heat exhaust.

    1 btu = 1 055.05585 joules

    is that answer for heat btus or cooling or just 1 btu in general

    A BTU is also the equivalent of 252 heat calories, not to be confused with the kilo-calories of food, and of approximately a third of a watt-hour. When speaking of cooling power, the BTU also works in reverse. The air-cooling power of an air conditioning system refers to the amount of thermal energy removed from an area. Hence a 65,000 BTU heater and a 65,000 BTU air conditioner are of roughly the same capacity and size. The higher the BTU output, the more powerful the heating or cooling system.

    When buying heaters, air conditioners, and barbeque grills, you often see it rated in BTU. That stands for British Thermal Units. This is similar to calories because it is based on the energy to heat water. But instead of metric units, it uses English units. A BTU is the energy needed to raise one pound of water 1 degree Fahrenheit. A pound is 454 grams of water and a Fahrenheit degree is 5/9 the size of a Celsius degree. So that means one BTU equals 454x5/9 or 252 calories. Often they rate these items in BTU but they actually mean BTU per hour, which is the rate of heating or cooling. This grill was listed as 48,000 BTU grill. That means it puts out 48,000 BTU of energy per hour. So it could raise the temperature of 1,000 lbs of water 48°F each hour. That's a lot of heating.

    Looks like heating and cooling are the same thing.

    Maybe the calories thing is your answer.
    Dardaigh

    BTUs, or British Thermal Units, is a unit of energy measurement, used to rate the power of air conditioners and heaters. One BTU denotes the amount of heat it takes to raise the temperature of 1 pound of water 1 degree Fahrenheit at an atmospheric pressure level of 1. A BTU is also equivalent to 251.997 calories of energy

    thank you so much you have helped me tremendously have a great day or evening
    Dardaigh

    Hope you got your answer. I tried my best...lol.
    Have a good evening too. :)

    thank you but thats not specific to my question
