Hi there.
00:03
In this question, we have a candy bar that has what appears to be a harmless 148 dietary calories.
00:16
All right, and we have several conversion factors here, so there are a few different directions we could go to solve this problem.
00:23
But what i'm going to do, first of all, is i'm going to use the one that allows me to convert from dietary calories to kilo calories.
00:31
A dietary calorie is actually a kilo -calorie.
00:38
So i'm using the first conversion we have there to convert from calories to kilo calories.
00:46
Then i'm going to go ahead and convert from kilo calories to actual calories.
00:52
So in one kilo calorie, we see down there the fourth conversion tells us that that is 1 ,000 calories.
01:01
And again, there are several different paths you can take using these equalities to get to the correct answer.
01:07
This is the one i am choosing.
01:09
All right, so now i have calories and i want to convert to joules.
01:14
So i see that one calorie is equal to 4 .184 joules...
