The British thermal unit (Btu) is the heat needed to raise the temperature of a pound of water by a Fahrenheit degree. Other substances, however, absorb heat at different rates, with each having their own specific heat capacity. You can use Btus to calculate their heat requirements as well...
BTU represents the energy required for heating a pound of water by one degree Fahrenheit. Typically every cooktop comes with a BTU rating, which you could find in its manual. For every 1 CFM, you would need a one-of-a-hundredth BTU. This small size is due to there being thousands of ...

Harvesting Btu: How to Extract More Heat from a Storage TankSiegenthaler, John
The BTU needed to cool down a room of known footage that can be calculated. According to The U.S. Department Of Energy recommendation for the size of room air conditioners: “…an air conditioner generally needs 20 BTU for each square foot of living space.” Based on room size, ceiling ...
BTU, which stands for British thermal unit, is how pool heaters are sized. One BTU (sometimes also written as Btu) is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Pool heater outputs range from 75,000 BTU to 450,000 BTU. The amo...
Answer #2: The CFM needed for a specific room depends on the size of the room and how often you want its air to be changed. This is the answer to the question:How many CFM do I need to give me the right ACH? The concept of ACH, or air changes per hour, is totally explained ...
I figure it had to be both because A/Cs have BTU ratings and they wouldn’t advertise the heat pumped out the exhaust. lol As for the HVAC ton, I do vaguely remember my father grumbling about something not being a ton over and over when he got the results from writing his heating ...
