اکثر پوچھے جانے والے سوالات
How many joules in a food label calorie?
One food Calorie on a label (which is really 1 kcal) = 4,184 joules. A 100-calorie snack = 418,400 joules.
Why use two different calorie definitions?
Confusion arises because food labels use kcal but write "calories" without the "kilo". Scientists prefer joules to avoid ambiguity.
How much energy do I burn exercising?
Varies by activity and person. Running for 30 min might burn 300–500 food calories (1.26–2.09 million joules).
