Q:

# How can you convert between BTUs and CFH?

A:

The British thermal unit, or BTU, is a unit of the energy needed to change the temperature of a pint of water by one degree Fahrenheit. One cubic foot, or CF, of natural gas can change the temperature equivalent to about 1000 BTUs. Therefore, a flow of 1 cubic foot per hour, or CFH, of natural gas is equivalent to providing approximately 1000 BTUs every hour.

The energy content of a natural gas depends on its composition, which means there is no universal conversion factor between volume and energy. Residential natural gas customers get a measure known as therms on their bills. One therm is equivalent to 100,000 BTUs. In the natural gas industry, MBTUs, which is the short form for one million BTUs, are also sometimes used to compare the energy content between various natural gas and fuels.

In 2009, on a daily basis, the average American home consumed 193 cubic feet of natural gas. Determining whether natural gas or heating oil is more efficient is a good exercise in energy efficiency. Assuming a 1025 BTU per cubic foot natural gas and that 81,300 cubic foot is consumed in a year, a total of 83,332,500 BTUs is consumed. Compare this to consuming 584 gallons of heating oil at 138,690 BTU per gallon, which yields 80,994,496 BTU. In this example scenario, natural gas is less efficient than heating oil at heating the home. The cost of the electricity can then be computed based on the total BTUs and a decision made on which fuel to use.

Use the standard temperature conversion formula to convert degrees of Celsius to degrees of Fahrenheit. Multiply by nine, divide by five and then add 32.

In order to convert 120 degrees Celsius to its equivalent temperature in degrees Fahrenheit, you need to apply the equation (9/5)C + 32 = F, where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit. The values 9/5 and 32 are constant, and they do not change regardless of the numeric value of the temperature. In this case, C = 120, so the formula becomes [(9/5) x (120)] + 32. The answer is 248 degrees Fahrenheit.
