You cannot do so directly. They measure completely different things.
Grams is a measurement for mass while kcal is a measurement of energy (or something like that). The point is they are two different measuring metrics for two different metrics. It will be like asking how to convert inches into minutes

∙ 15y agoGrams are a mass unit and joules an energy unit so the only way to convert between them is E=mc2.
1 Joule = 1kg * m2/s2
Speed of light = 3.00×108 m/s
1 gram = (3.00×108)2 / 1000 1 gram = 9x1013 Joules

The specific heat of gold is 0.131 Joules per gram. Celsius How much energy is required to heat 1.3 grams of gold from 25 Celsius to 46 Celsius?
0.131 joules/gram'C x 1.3 grams x (46-25)'C = 3.5763 joules
The temperature of 15 grams of water is increased by 3.0 Celsius degrees How much heat in Joules was absorbed by the water?
I assume you mean 30o Celsius. Use this formula.q(joules) = mass * specific heat * change in temperatureq = (15 grams water)(4.180 J/gC)(40o C - 30o C)= 627 joules==========( perhaps 630 joules to be in significant figures territory )
How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams for 0.0?
46 calories (or 192, 464 joules) for each Celsius degree.
What amount of heat energy is required to raise the temperature of 45 pounds of lead from 62 degrees to 100 degreesF?
Specific heat of lead = 0.160 J/gC 45 pounds (454 grams/ 1 pound) = 20430 grams Use. q(Joules) = mass * specific heat * change in temp. q = (20430 grams)(0.160 J/gC)(100 C - 62 C) = 1.2 X 10^5 Joules ------------------------- or ------------------------- 1.2 X 10^5 Joules (1 calorie/4.184 Joules) = 29688 calories
What energy is measure in?
A: Energy is measured in joules and kilojoules. One joule is the amount of energy needed to lift 100 grams to 1 kiliogram.
How many grams is equals 1 joules?
0000000000000000.11 joules
How many joules are in 1500 grams?
Voltage is electrical pressure and Joules is a power rating so other info is needed
How do you Convert 40.79 kilojoules per mole to joules per grams?
40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams
What is the measurement for specific heat?
The unit for specific heat is Joules/g-Kelvin or it can be Joules/g-Celsius J= Joules g= Grams C= Celsius
What is the total amount of heat energy in joules absorbed by 25.0 grams of water when the temperature of the water increased from 24.0 C to 36.0 C?
2520 Joules = (X)(4.180J/gC)(30C-10C) 2520J = 83.6X 30.14 grams of water.
How many joules are needed to melt 2 grams of water?
2,26 Kj are necessary
How do I convert the enthalpy of vaporization of water in joules per gram from kiloJoules per mole?
Lets say, for example the enthalpy is equal to 1200 joules/gram. You take 1200 joules/gram * (# of grams)/one mole [now you can cancel grams and it is now joules/mole.] Then convert the answer to kilojoules by dividing by 1000.
The specific heat of gold is 0.131 Joules per gram. Celsius How much energy is required to heat 1.3 grams of gold from 25 Celsius to 46 Celsius?
0.131 joules/gram'C x 1.3 grams x (46-25)'C = 3.5763 joules
A sample of H½O with a mass of 46.0 grams has a temperature of?
96.3 Joules
how many grams iron will absorb 900 joules of heat and only change temperature by .2 degrees?
200 grams
When 20 grams of water is cooled from 20 C to 10 C the number of joules of heat released is?
200 calories, or approx. 47.84 joules
How many joules are necessary to heat a sample of water with a mass of 46.0 grams from 0.0?
46 calories (or 192, 464 joules) for each Celsius degree.
