>AJH, >Are we mixing calories per gram and kJ per kilogram I hope not; I was trying to stick with Joules, kilo Joules and Mega Joules. Joule was the chap that established the relationship between shaft power and rate of heat production, so he measured what motion energy he had to put into boring a cannon and how much that raised the temperature of the cannon. A he established the relationship the SI unit of work/energy was named after him. A Joule is the work necessary to move a force of 1 Newton through 1 metre. Do that work in 1 second and your power is one Watt. Your calorie is the amount of heat necessary to raise 1g of water through 1 degree centigrade. You need to deliver ~4.2 Joules to do the same so to raise 1kg of water through 1 degree centigrade requires 4.2 times 1000 Joules.
