difference between cal and kcal ,serious answers plz?

Answer 1

1 kcal=1000cal

Answer 2

A calorie is a unit of measurement for energy. The unit's name is French and derives from the Latin calor (heat). In most fields, it has been replaced by the joule, the SI unit of energy.
In scientific contexts, the name "calorie" refers strictly to the gram calorie, and this unit has the symbol cal. SI prefixes are used with this name and symbol, so that the kilogram calorie is known as the "kilocalorie" and has the symbol kcal.

The small calorie or gram calorie approximates the energy needed to increase the temperature of 1 g of water by 1 °C. This is about 4.185 J. The small calorie or gram calorie approximates the energy needed to increase the temperature of 1 g of water by 1 °C. This is about 4.185 J.

The large calorie or kilogram calorie approximates the energy needed to increase the temperature of 1 kg of water by 1 °C. This is about 4.185 kJ, and exactly 1000 small calories.

Answer 3

a calorie, in scientific terms, is the amount of energy required to raise one gram (or ml) of water by 1 degree centigrade. A kcal, otherwise known as a food calorie, is 1000 cals. When you see calories on the back of food labels, they are kcals.

(this also means that you burn more calories by drinking ice water vs tap water, because your body must burn more calories to raise the cold water to body temperature). If you drink a liter of ice water, you will need to burn 37,000 calories just by drinking it and heating it up. 37 food calories. Neat!

Answer 4

A calorie is the amount of energy required to raise 1 gram (or 1 millilitre) of water by 1 degree centigrade. This is a small amount of energy, so for food labelling purposes, the calorific value is quoted in Kilocalories, or 1,000 calories, which is the amount of energy required to raise 1 Kilogram (or 1 litre) of water by 1 degree centigrade.

Hope that helps

Answer 5

calorie (abbrev. cal; pl. calories; also small calorie): 1. A unit of energy often used when measuring the energy content of food. One calorie equals 4.187 joules or 0.003969 British thermal units (Btu). 2. The amount of energy needed to raise the temperature of one gram of water one degree Celsius.

Food calorie (abbrev. Cal, kcal; also Calorie [written with a capital C], Kilocalorie, Large calorie): A unit of energy equal to one kilocalorie. The food calorie is often used when measuring the energy content of food.

Answer 6

kcal=KILOcal, so its 1000 cal
like kilogram and gram
tricky thing is, on all the foods everything is in kcal, so you are really eating a lot more calories than you think ;)

Answer 7

cal = calorie unit of energy
kcal = Kilo calorie also unit of energy but 1000 times more than cal

Answer 8

cal is the amount of heat required 2 raise d temperature of 1g water by 1 c

kcal is the amount of heat required 2 raise d temperature of 1kg water by 1 c

Answer 9

cal = calories

kcal = kilo calories

1kcal = 1000 cal

Answer 10

The difference is K
