How many chocolate bars would stack to your weight?
A standard chocolate bar weighs about 50 g. A 75 kg adult equals 1,500 chocolate bars. Stacked end to end (bars are ~80 mm long) that\'s a 120-metre line of chocolate.
Why 50 g is the magic number
Most of the world\'s famous chocolate bars cluster around 45–55 g, which is no accident — it\'s the weight food psychologists found to be the most satisfying single serving for a snack. Larger bars (sharing size at 90–110 g, or "king size" at 70–90 g) exist but the standard snack bar has stayed remarkably consistent since the 1930s.

Chocolate as energy
Chocolate is one of the most calorie-dense foods on Earth at roughly 5 kcal per gram. Your body weight in chocolate would supply around 375,000 kcal — enough food energy to live on for about six months at normal maintenance. Chocolate gets its density from the combination of sugar, milk solids and especially cocoa butter, which is essentially pure fat at 9 kcal per gram.
