A fast food item contains 544 nutritional calories. Convert this energy to calories and to Joules
544 "nutritional calories" = 544 kcal.
There are 4.184 J in a calorie.
To convert nutritional calories to calories, you simply need to multiply the value by 1,000.
Step 1: Multiply 544 nutritional calories by 1,000.
544 nutritional calories * 1,000 = 544,000 calories
Therefore, 544 nutritional calories is equal to 544,000 calories.
To convert calories to Joules, you can use the conversion factor of 1 calorie = 4.184 Joules.
Step 2: Multiply 544,000 calories by 4.184.
544,000 calories * 4.184 Joules/calorie = 2,273,216 Joules
Therefore, 544 nutritional calories is equal to 544,000 calories or 2,273,216 Joules.
To convert nutritional calories to calories and to Joules, we need to understand the conversion factors involved.
1 nutritional calorie (Cal) is equivalent to 1 kilocalorie (kcal) or 1000 calories (cal).
To convert calories to Joules, we need to know that 1 calorie is approximately 4.184 Joules (J).
Now, let's convert the given 544 nutritional calories to calories and Joules:
1. Conversion to calories:
Since 1 Calorie (nutritional calorie) = 1000 calories, we can convert 544 nutritional calories to calories by multiplying it by 1000:
544 nutritional calories * 1000 = 544,000 calories
Therefore, 544 nutritional calories is equal to 544,000 calories.
2. Conversion to Joules:
Since 1 calorie (cal) ≈ 4.184 Joules (J), we can convert 544,000 calories to Joules by multiplying it by 4.184:
544,000 calories * 4.184 J/cal ≈ 2,271,296 Joules (J)
Therefore, 544 nutritional calories is approximately equal to 2,271,296 Joules (J).
So, the given fast food item contains 544 nutritional calories, which is equivalent to 544,000 calories and approximately equal to 2,271,296 Joules (J).
