1 calorie = 4.1858 joules
1 joule = 0.2389029576186153 calories
As an example, convert 5 calories to joules.
1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules.
So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.

Oh, dude, converting Joules to nanometers? That's like trying to turn a potato into a unicorn. It's not really a thing, you know? Joules measure energy, while nanometers measure length. It's like comparing apples to oranges, man. Just keep those units in their own lanes and you'll be golden.
one thousand joules equals a KJ
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
No, to convert from cal. to joules 1 cal. = 4.18400 joules , then 1KCal = (4.18400 *10^-3) joules so 3.25 kcal doesn't equal 3.25 Joules
To convert 6.5 kilocalories to joules, you multiply by 4184 since 1 kilocalorie is equal to 4184 joules. Therefore, 6.5 kcal is equal to 6.5 x 4184 = 27,164 joules.
To convert calories to joules, you can use the conversion factor 1 cal = 4.184 J. Therefore, 1.987 cal is equal to approximately 8.32 J.
1 calorie = 4.18 joules; 470 joules = 112 cal; 1 nutritional cal(Cal) = 1 kilo-cal = 1000 cal; 470 joules = 0.112 Cal
1 cal=4 joule. 84 joules=84/4=21 cal
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
Joules (J) or kilocalories (cal) (kcal in Europe)
Depends on the type of calorie you're asking about. A "small calorie" which uses the symbol 'cal' is equivalent to about 4.18 Joules. A "large calorie" which uses the symbol 'Cal' is equivalent to about 4.18 Kilo Joules.
E = mass x sp ht x Δ°t (Finding Energy)where E (Energy) or Q (Quantity of Heat), mass (g), sp ht (aka specific heat, J/g°C*[typical] or cal/g°C or kcal/g°C), and Δ°t (temperature change). Finding Temperature ChangeDivide energy by mass multiplied by specific heat. Δ°t = Energy-- Mass * sp htIn order to find the final temperature (if problem is asking for this), add or subtract the original temperature and the new temperature together.Tf = original temperature +/- new temperatureIf energy is added, the temperatures will be added together; if energy is removed, the temperatures will be subtracted.Finding MassDivide energy by specific heat multiplied by temperature change. Mass = Energy------- sp ht * Δ°tFinding Specific HeatDivide energy by mass multiplied by temperature change. Sp ht = Energy------- Mass * Δ°tConverting Form of Energy (joules, kcal, and cal)Sometimes a problem will have E be shown in cal/g°C or kcal/g°C but will be asking for Joules or even vice versa. This means a conversion has to take place.
