Does 1 joule equal 3 calories?
Because heat is a form of energy, it can be converted to joules. If 4.186 calories are in one joule, then 0.2389 calories are in one joule. To find calories per joule, divide calories by joules: 1/4.186=0.2389 cal/joule. Because 4.186 joules is equal to one calorie, this is the number of calories in one joule.
How many calories is 1 kg of J?
| Joules | Kilocalories |
|---|---|
| 1 J | 0.000239 kcal |
| 2 J | 0.000478 kcal |
| 3 J | 0.000717 kcal |
| 4 J | 0.000956 kcal |
How do you convert kJ to calories in chemistry?
To convert a kilojoule measurement to a calorie measurement, multiply the energy by the conversion ratio. The energy in calories is equal to the kilojoules multiplied by 239.005736.
How many joules are contained in a snack that is labeled 230 calories?
You have 960 J in that many calories.
Why is a calorie equal to 4.184 J of energy?
(a) The ‘Thermochemical calorie’ was defined by Rossini simply as 4.1833 international joules in order to avoid the difficulties associated with uncertainties about the heat capacity of water. It was later redefined as 4.1840 J exactly.
How many calories make up a calorie?
One calorie is equal to 4.184 joules, a common unit of energy used in the physical sciences. Most of us think of calories in relation to things we eat and drink, as in “This can of soda has 200 calories.” It turns out that the calories listed on a food package are actually kilocalories (1000 calories = 1 kilocalorie).
How many kcal are in a calorie?
The kilocalorie (symbol:kcal) is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. The kilocalorie is thus equal to 1000 calories. This tool converts kilocalories to calories (kcal to cal) and vice versa. 1 kilocalorie = 1000 calories.
How do you convert calories to kilo calories?
…
Kilocalories to Calories.
| 1 Kilocalories = 1000 Calories | 10 Kilocalories = 10000 Calories | 2500 Kilocalories = 2500000 Calories |
|---|---|---|
| 9 Kilocalories = 9000 Calories | 1000 Kilocalories = 1000000 Calories | 1000000 Kilocalories = 1000000000 Calories |

Can you burn 3500 calories a day?
It is possible to burn 3,500 calories a day (or lose a pound in one day) by creating an energy deficit. To do so, you must eat less and work out more or at a higher intensity. However, that weight loss would be from both diet and exercise, not just one 3,500-calorie-burning workout.
How many pounds is 2800 calories?
| Pounds | Calories |
|---|---|
| 0.7 lb | 2,450 kcal |
| 0.8 lb | 2,800 kcal |
| 0.9 lb | 3,150 kcal |
| 1 lb | 3,500 kcal |
How can I lose a lb a day?
You need to burn 3500 calories a day to lose one pound a day, and you need anywhere between 2000 and 2500 calories in a day if you are doing your routine activities. That means you need to starve yourself the whole day and exercise as much as to lose the remaining calories.
What is the value of 104 calories in joules J )?
104 calories = (104) (4.18) = 434.72 joules. – Therefore the number of joules for 104 calories is 434.72 joules. – Joules are different from calories, both are not the same.
How many joules are in a apple?
The potential energy of an apple is 4.5 joules.
How do you calculate joules?
Multiply watts by seconds to get joules.
A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.
Which one is greater joule or calorie?
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.
How many joules are in 1 calorie The specific heat of water is 4.184 J GC?
1 Expert Answer
one calorie is equal to 4.184 joules. B. The specific heat of water is 1 calorie per gram-°C. The heat required to raise the temperature of 2000 g water by 20°C is 1.00 cal/g-C x 2000 g x 20 °C = 40000 calories or 167360 joules.
How many kJ is 2000 calories?
One calorie (kilocalories) is 4.18 kilojoules. Or to put it differently, 1kcal = 4.18kj. This therefore means that to convert 2000kcal into kilojoules, you would multiply 2000kcal by 4.18. This would make it 8,360kj.

How many kJ should I burn a day?
In order to achieve weight loss an individual needs to consume less energy (kilojoules) than the will body burn. For example if an individual needs 8,700 kilojoules per day to maintain weight, reducing daily intake to 6,600 kilojoules (assuming exercise stays the same), should provide around 500g per week weight loss.
Is kJ same as calories?
Calories and kJs both represent energy in the same way that centimetres and feet both measure height. The kilojoule (kJ) is an International system of units (SI) measurement whereas Calorie is a measure of energy using the metric system.
