Conversions Regarding the Metric System and some Associated Formulas By Toomuchswag Sources: My Chemistry Notes and http://www.simetric.co.uk/siprefix.htm for some verification Most of the world besides the United States uses the metric system, a much simpler measuring tool according to many. The Metric system works in powers of ten: The prefixes work like this: Kilo Hecto Deca R (this is the regular unit, be it meters, grams, etc. we have given it the letter R) Deci Centi Milli Some important formulas: Density: Mass/Volume 1calorie or cal is the amount of energy required to raise the temperature of water by 1 degree Celsius
