## How do you go from kilocalories to joules?

How to convert from joules to kcal

1. Joules to thermochemical / food kilocalories. 1 kcalth = 4184 J.
2. Joules to international kilocalories. 1 kcalIT = 4186.8 J.
3. Joules to 15°C kilocalories. 1 kcal15 = 4185.5 J.
4. Joules to 20°C kilocalories. 1 kcal20 = 4182 J.

Is J same as Cal?

The energy in joules is equal to the calories multiplied by 4.184. For example, here’s how to convert 5 calories to joules using the formula above. Calories and joules are both units used to measure energy.

### How much is 1 kJ equal to in J?

Kilojoules to joules conversion table

Energy (kJ) Energy (J)
1 kJ 1000 J
2 kJ 2000 J
3 kJ 3000 J
4 kJ 4000 J

How many kcal do we need per day?

As a guide, an average man needs around 2,500kcal (10,500kJ) a day to maintain a healthy body weight. For an average woman, that figure is around 2,000kcal (8,400kJ) a day.

## Is kcal smaller than Cal?

Thus, 1 kilocalorie (kcal) = 1000 calories (cal). By convention in food science, the large calorie is commonly called Calorie (with a capital C by some authors to distinguish from the smaller unit).

Is a calorie bigger than a joule?

The unit joule is defined in terms of work done. However, the calorie is defined in terms of the heat energy as follows: One calorie is the amount of heat required to raise the temperature of a one gram of water by one degree Celsius. Hence, we see here that the calorie is numerically, greater than the joule.

### Is kJ bigger than J?

Thus, a kiloJoule (kJ) is 1000 Joules and a megaJoule (MJ) is 1,000,000 Joules. A related unit is the Watt, which is a unit of power (energy per unit time).

Should I eat the calories I burn?

There’s no way around it. Once your body’s energy needs are met, extra calories are stored for future use — some in your muscles as glycogen, but most as fat. Thus, eating more calories than you burn will cause you to gain weight, whereas eating fewer than you need will cause weight loss ( 4 ).
