Question

its so hard to calculate ?!

Answer 1

1 pound is about 454g (not "kg")

how many caloried do u need to make 1kg on your own body?
that's depends.

Answer 2

Not sure of the context, so this may not be a meaningful answer. However, it is a rule of thumb that 1 pound of body fat represents 3600 kcal of food energy (what we call 'calories' are actually kilocalories). (This isn't precisely true because the body also expends energy in the storage process.) If 1 kg = roughly 2.2 lb, then 1 kg of fat is about 7920 kcal, or 'about 8000 calories' to be less precise.

If you're talking mass to energy conversion, you need a different formula that I don't even want to try using because it would make my brain hurt. If this is about some other chemical reaction, you'll have to provide a lot more detail.

Answer 3

Calories are the energy that potentially can be gained by eating a certain amount of food. The amount of pounds that those calories translate into in your body depend on the level of activity you are involved with.

More activity equals more use of calories, less activity equals less use of calories. Any excess food units that you don't use as calories will be stored in the body (as fat or pounds as you say) until a later time. Exercise isn't the only thing that uses calories, however, so don't go by the exercise machine readout. Standing, thinking, walking etc. all use calories.

Answer 4

If you are interested in losing weight, one pound of fat is about 3,500 kilocalories ( kilocalorie is the "Calorie" used in food tables). So at 2.2 pounds per kilogram, you'd need to get rid of 7,700 Calories.

In physics, using Einstein's formula of e=mc^2, e=1 kg x (299,792,458 m / s)^2 = 8.99 x 10^16 joules. Since 1 joule = 0.239005736 calories, this is 2.14807643 × 10^16 calories, or 2.14807643 × 10^12 kilocalories.

It's a good thing for dieters that our metabolism isn't efficient.

Answer 5

Calories and Kg are 2 different things. Kg is a measurement of mass, whereas calories is a measurement of heat. You cannot calculate the number of calories in 1kg; unless you know the caloric intake, our output of a given rxn. For example, 1 gram of HCl mixed with H20 will output 5cal/g. (this is just an example). Therefore 1kg would yield 5,000calories. Hope this helps =)

Answer 6

a calorie is a unit of energy - weight is a unit of mass. You can't really convert one to the other. 1 lb of cheesecake has more calories than 1 lb of carrots.

Answer 7

1000 calories = 1kg
1kg =2.2 lb

Answer 8

This depends on the substance. Each substance has its own enthalpidic properties.

Answer 9

0.454 kg
