1 calorie equals 4.18400 joules so multiply 1.987 by 4.184.
1.987 cal equals 8.313608 J.
First scientists used calorie as the unit of heat energy. One calorie is the amount of heat required to raise the temperature of one gram of water through one degree celcius. So 1000 cal is taken as kilo calorie. Even now a days we use such units in case of biological energy. Later scientists have found that heat is also a kind of energy which is closely related to mechanical energy as 1 cal = 4.18 joule So k cal requires 4180 joule of energy. This is what we call mechanical equivalent of heat energy. So at present stage we use only joule as the unit of heat energy. Especially in chemistry they use kilojoule/mole etc.
Heat of fusion is absorbed Q = mLf = 75x 80 = 6000 cal just to melt the ice Heat is absorbed to change temp Q = mC(delta)T = 75 x 1 x (90 - 0) = 6750 cal Total heat = 6000 + 6750 = 12750 calories
its temperature dependent
The unit is joule (J).
One was James Prescott Joule. Please see the link.

This conversion would be easy, IF there were a way to convert hours to grams.Unfortunately .....
There is no connection. Litre is volume, joule is a unit of energy.
A calorie is greater - it is equal to about 4.2 joules.
1 Joule = 0.2390 cal (calorie) or 4.18 J=1 cal
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.
Joules x 0.000000278 = kW/h
1 litre diesel in joules
Cal Clutterbuck was born on 1987-11-18.
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
It was not designed for 25 cal ammunition.
