Kilotonne and megatonne may be used as metric for measuring energy release. This makes use of the unit by connecting it with the explosive TNT, as a way of calculating the force of an explosion. A metric ton of TNT releases roughly 4.19 X 10^9 Joules of energy, with a kilotonne releasing 4.19 X 10^12, [...]

Its solubility in alcohol and water had led to great utility in the manufacturing of products. Glycerin is used in a large number of cosmetic and household products, such as toothpastes and shampoo.
