II1 UNIT CONVERSIONS This is a mathematical process that can be used to solve questions in MANY other subjects besides chemistry I DONT CARE if you have a different method for solving these questions . : Unit conversions This booklet will provide an overview of the unit conversions for n ursing students. If you have any problems in answering the questions within the booklet please contact skil III. Unit Conversions . (p.39-41). SI Prefix Conversions. Dimensional Analysis. A. SI Prefix Conversions. 1. Find the difference between the exponents of the two prefixes.. 2. Move the decimal that many places.. Practice Using the Factor-label Method. When converting from one unit to another (i.e. kg .  g, or feet  meters), we use . Conversion Factors. Conversion factors tell us the equivalent magnitude in the new unit. 57 1 Astronomical Unit = 1.0 AU = 1.49 x 10 8 1 Liter = 1000 cm3 1 inch = 2.54 centimeters 1 kilogram = 2.2 pounds 1 Gallon = 3.78 Liters 1 kilometer = 0.6 The universally accepted system of measurement is the SI System, the System Internationale d’Unites, or the International System, also known as the metric system. The metric system is based on the unit ________.. Chapter 4. MAT 119. Objectives. Recall from memory the metric and household approximate equivalents.. Convert among units of measurement within the same system.. Convert units of measurement from one system to another.. T. Trimpe 2008 http://sciencespot.net/. So How Do I Do A Metric Conversion?. We will be using a method called The Stair-step Method of Metric Conversion.. It requires two things; one, that you be able to count to 6, and two, that you know your left from your right.. There have been many . serious incidents. that have resulted from errors in converting between systems of units.. Air Canada Flight 143. (Google it for more details). Unit Conversion Accidents. $125 million Mars Climate Orbiter.. Necessary in science and engineering to work across different systems of measurement or to express quantities in different units within a single system. Conversion factor . Multiplied by a quantity to convert the quantity to . Solve unit conversion problems.. Use dimensional analysis to convert between metric units.. Determine the meaning of common metric prefixes.. Use dimensional analysis to convert between metric and non-metric units.. What makes a measurement useful? . It must include a number and a unit.. A standard must be used. An exact quantity that people agree to use for comparison. . 2. SI System. Scientists use SI system. International System of Units. Introduction to Engineering Design. Unit Conversion. Converting units is necessary in science and engineering . to work across different systems of measurement. SI to US like meters to feet. or to express quantities in different units within a single system . ODE. Stochastic. Units. With concentrations* (ODE simulations only):. concentrations (. eg. moles/liter) for species. Unit concentration / unit time for reactions. With particles (ODE or stochastic):.  . What’s a mole?. The . mole. is a unit of . measure. .. Just like meters tells us . length. and seconds tells us how much . time. , . the . mole. measures an . amount. . (how much).. Units of measure similar to mole include: .
