**BTUs are based on the test weight and moisture content of the corn.**

**Efficiency of your stove, furnace, or boiler affects the exact number**

For our discussion, the two most important factors affecting corn's BTUs

are moisture content and test weight.

Moisture Content

Moisture subtracts directly from the overall weight of the corn. For

example, if you have a pound of corn at 13% moisture, subtract 13 from

the pound which therefore equals .87 pounds of zero percent moisture

corn. 13% of a 40 pound bag gives the consumer 34.8 pounds of zero

percent moisture corn. Therefore it is evident that moisture is a key

component in the amount of BTUs corn delivers.

Test Weight

The other variable is test weight. Test weight is the measure of the quality

and the number of BTUs per pound. Seed corn, cultivation, and weather

determine the test weight per bushel. Higher test weights yield a larger

BTU per pound. Typically test weight can range from 50 to 58 pounds per

bushel, which corresponds to 7600 to 8500 BTUs per pound of zero

percent moisture corn.

BTUs Estimation

When taking into consideration moisture and test weight we can fairly

estimate the BTUs per pound and bag. Kernel's Corn average test weight

this year was 57.1 pounds per bushel, which equates to approx. 8,410

BTUs per pound at zero percent moisture. At 13% you have .87 pounds

of zero percent moisture corn which equals 7,316 BTU's per pound,

because of the moisture content there is a loss of 1,094 BTUs per pound.

Therefore, the total energy per bag would be 40 pounds at 13% moisture

times 7,316 or 292,640 BTUs per bag. Let’s compare that to 3 gallons of

LP fuel. Three gallons of LP equals 274,500 BTUs. The average cost of

LP has been $1.80 per gallon or $5.40 for three gallons. Therefore a 40

pound bag of corn will yield 18,140 more BTU's than 3 gallons of LP.

Kernel's Corn™ tries to give fair estimated values of BTUs per pound and

bag.
