All right, watts are a unit of power, our power.
00:10
So energy used over time is power.
00:30
So we're asked to take 2 ,000 kilocalories of energy, and divide that by one day and convert these units to watts.
00:54
So all we got to do is use some conversion factors here.
00:59
Okay, one day is 24 hours.
01:09
And one hour is 3 ,600 seconds.
01:22
All right, if i want to go from kilo -calories to just calories, so i would need 1 ,000 calories to make one kilocalorie.
01:39
And so now i need to figure out how many calories are in a jewel.
01:49
So calories and jules.
01:53
So i'm going to look that up in a conversion chart.
01:56
I see that 4 .184 jules in one calorie.
02:09
All right...
