Question

The average person in the United States uses 330,000,000 Btu/yr. Most of us are more familiar with calories though, mostly when we think of food. Conversion factors to move between units are provided in the textbook appendix (or even through a simple internet search), and it turns out 1 Btu is equal to a little over 200 calories. After you look up the exact conversion, use it to calculate how many "equivalent food calories" we use every year. Keep in mind that food calories are actually "kilo calories", so be sure to reduce your answer by 1,000.

56,000 calories

6 million calories

83 million calories

143 million calories

56,000 calories

Explanation / Answer

c.We know that 1 BTU=0.252 KCal

Therefore for 330,000,000 BTU=0.252*330,000,000

=83,160,000 calories

or approximately 83 million calories
