Hoppe's #9 is a gun oil, not a stock finish, meant for lubricating metal parts. If you have a satin finish on your stock, that gun oil is slowly eating that finish away. Switch over to a linseed oil based or carnuba wax based stock rub. It will maintain your stock's finish and protect it as well.
Calories vs Kilojoules. Calories and kilojoules are units to measure the energy. Commonly, these two words are used in measuring food energy. It is necessary to indicate the amount of energy contained in each food item on their packagings.
A Joule, J, is the SI unit of energy and is defined as one kgÂ·m2/s2. The prefix kilo means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence per mole. calorie was originally defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius. One calorie = 4.184 J. One kcal = 1,000 cal. When we count calories in our food, we are actually referring to kilocalories; e.g. 1 dietary Calorie = 1,000 cal = 1 kcal.
