Dietary guidelines suggest an intake of about 1903 food calories per day for an adult human. There are about 4184 joule in one food calorie. How many watts powers an adult human throughout the day?

1903 cal * 4184 j/cal = 7962152 j      per day

 

1 watt = 1 j / sec

 

7962152 j / (3600*24 sec)= 92.15 watts         (3600 * 24 is the number of seconds in a day)
