Make the conversion
8.5 x10^2 cal to Calorie
4.5x10^-1kj to calories
8.5E2 cal x (1 Cal/1000 cal) = ?
0.45 kJ = 450 J
450 J x (1 cal/4.184 J) = ?
1 calorie = 4.184 joules. Basic dimensional analysis. In the 1st conversion, is Calorie referring to a nutritional calorie? If so, 1000 cal = 1 nutritional calorie. Also, basic dimensional analysis.
To convert 8.5 x 10^2 cal to Calories, you need to divide by 1000, since there are 1000 calories in 1 Calorie (also known as a kilocalorie).
8.5 x 10^2 cal / 1000 = 0.85 Calories
Therefore, 8.5 x 10^2 cal is equal to 0.85 Calories.
To convert 4.5 x 10^-1 kJ to calories, you need to multiply by 4.184, since 1 kJ is equal to 4.184 calories.
4.5 x 10^-1 kJ * 4.184 = 1.8768 calories
Therefore, 4.5 x 10^-1 kJ is equal to 1.8768 calories.
To convert from calories (cal) to Calories (Cal), you need to divide the value by 1000.
For example, to convert 8.5 x 10^2 cal to Calories, you would perform the following calculation:
8.5 x 10^2 cal / 1000 = 0.85 Cal
Therefore, 8.5 x 10^2 cal is equal to 0.85 Calories.
Now, let's move on to the second question.
To convert from kilojoules (kJ) to calories, you need to multiply the value by 239.
For example, to convert 4.5 x 10^-1 kJ to calories, you would perform the following calculation:
4.5 x 10^-1 kJ * 239 = 107.55 calories
Therefore, 4.5 x 10^-1 kJ is equal to 107.55 calories.
