How many joules are in 1 kcal?

The conversion is 4.2 Joules per calorie, so 4 kcal is 16.8 kJ.

1 kcal equal 1 000 calories or 4,184 joules. 1 calorie is equal to the heat needed to increase the temperature of 1 g water with 1 0C.

no, that's a conversion factor of 4.184

100 g have 300 kcal, http://www.thefruitpages.com/contents.shtml

1 calorie is 4.18 joules.

1 Kilojoule = 1000 Joules

1 calorie = 4.184 joules

1Kg fat about 7000kcal. NO ,IT IS NOT. 1 g OF FAT HAS 9 kcal /g. it is obvious that 1000g (1 kg ) of fat => 9000kcal!

1 W = 1 J/s 4190 J = 1 kcal 1200 J/s * 1 kcal/4190 J =0.286 kcal/s =17 kcal/min. Aren't you glad you don't have to run that hair dryer by pedaling a bicycle?

1 calorie = 4.18 joules; 470 joules = 112 cal; 1 nutritional cal(Cal) = 1 kilo-cal = 1000 cal; 470 joules = 0.112 Cal

1 Kilojoule is equal to 1000 joules. So, 980 kilojoules x 1000 joules per kilojoule = 980000 joules.

•3,500 kcal = 1 lb. of fat

you need to lose 7000 kcal of fat to lose 1 kilo fat, else it's 9000 kcal with water.

69 kcal per 1 oz.

1 kWh = 3.6 x 106 joules. In engineering notation, that's 3.6E6.

One foot-pound of force equates to about 1.355818 joules.

roughly 25 calories, 1 calorie is roughly 4 joules.

This question is impossible to answer because it depends on WHAT they are teaspoons of!

It may be better answered by asking it backwards: "How many Joules are in a kWh?" 1 Joule is 1 Watt-Second. Knowing this, you can derive that 3,600 Joules = 1 watt-hour. 3,600,000 Joules = 1 kilowatt-hour. To answer your original question, there are 1/3,600,000 kWh in a joule.

The two main units of Energy are the Joule and the Calorie. The Joule is normally represented as the KiloJoule (kJ), which is equivelent to 1000 J. The Calorie is represented as Kcal. 2000 Kcal (calories) is given as the Guideline Daily Allowance for most adults. 1 calorie = 4.184 J or equivalently, 1 kcal = 4.184 kJ Google calculator: http://www.google.com/search?q=1+calorie+in+joules&btnG=Search Wiki Joule entry: http://en.wikipedia.org/wiki/Joule Wiki Calorie entry: http://en.wikipedia.org/wiki/Calorie

Well the average apple is about 120 calories and 1 calorie is equal to a little less than 4.2 joules. Therefore an apple contains approximately 500 joules of energy.

35 kilocalories (kcal) equals about 0.40705-kilowatt hours (kWh). The conversion base is for 1 kcal there is 0.001163 kWh. Converting the kilocalories to watt-hours is 40.705.

1,428 joules.

There are 1000 joules in a kilojoule

There are 1000000 or 1 million joules in a megajoule. See the related link for conversion charts and more information.

No there's not. Except on the back of food packets it is called Kcal's instead of calories. This answer is wrong. A food, or dietary Calorie is equal to 1000 calories, which is 1 Kcal (kilocalorie). A capital C is also used to designate a Kcal, or 1000 small calories. A small calorie is designated by a small c, and is equal to the amount of heat required to raise the temperature of 1 cubic…

It takes 4186 joules to raise the temperature of 1 kilogram of water by 1 degree Celsius. The mass does make a difference.

1 watt = 1 joule per second

lol Mr.Burbank.

6 kcal / tsp

24 joules is 5.7323015 calories.

There are 3.87 kcal per gram of sugar, so the answer depends on the size of the sugar packet, which is apparently not standard. Packets tend to vary from 2-6 grams. According to the USDA website, they list 2.8g packet = 11 kcal Which would yield 16 kcal/ 4.2g teaspoon, and ~23 kcal/6g packet. Examples: "Sugar in the raw" brand has 5g = ~19 kcal Domino brand packets have 4g = ~15 kcal

Mayonnaise is almost pure fat. That being said it contains 9 kilocalories per gram. So, 1 kilogram would have 9000 Kcal. * a kilocalorie: kcal or food calorie is the standard measure of calorie content of foods.

148 calories is 619.6 joules. Since one calorie = 4.18 joules then you multiply that number by 148 and you get 618.64 joules (619 rounded)

1261 kcal in a pint

About 120 kcal.

Approx. 250 kcal.

k signifies "multiplied by one thousand", so 1000 calories is one kcal. Note, however, that dietetic "Calories" are already equivalent to kcals. They are actually exactly the same. kcal is kilocalories. Sometimes the term Calories is also used with "C" in uppercase. Both are correct and 1 kcal = 1 Cal. When we loosely say 1 Calorie, actually we mean 1 kilocalorie.

1 kilocalorie = 4186.8 joules, and 1 joule/sec = 1 watt. So 1 kwh = 1000 x 3600 watt.secs = 3.6 x 106 joules. So answer = 4186.8/(3.6 x 106) = 1.163 x 10-3 kwh. This could also be expressed as 4.2 kwsec You could check this directly using an electric kettle. Put in 1 liter of water (1 Kilocalorie will heat this by 1 deg celsius) Note the kettle wattage, and the cold water…

The number of joules to raise one gram of water by one degree Celsius is 4.2 Joules. The total number of joules needed then is 95,088 joules.

251 joules = 60 calories.

167.2 joules

5 x 10 ^ 4 Joules

10 - 20 calories per packet There are 3.87 kcal per gram of sugar, so the answer depends on the size of the sugar packet, which is apparently not standard. Packets tend to vary from 2-6 grams. According to the USDA website, they list 2.8g packet = 11 kcal Which would yield 16 kcal/ 4.2g teaspoon, and ~23 kcal/6g packet.

Fat free feta has 40 kcal for 1/4 c.

60,8 Kcal/200 ml

A 58g bar has 260 kcal.

"Kilo" means "one thousand", so kilojoule is a thousand joules.

The prefix mega- means million. There are one million joules in a megajoule.

4 calories per one gram of carbohydrates. == == A single gram of carbohydrates contains roughly four calories of energy. (Proteins also contain 4 kcal/gram; fats contain 9 kcal/gram and ethanol contains 7 kcal/gram.)
