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 . 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 II.1 UNIT . CONVERSIONS. This . is a mathematical process that can be used to solve questions in MANY other subjects besides chemistry. I DON’T CARE if you have a different method for solving these questions, . 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 ________.. © 2012 Project Lead The Way, Inc.. Introduction to Engineering Design. Design Process and Engineering Notebook. Use the engineering design process.

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.. Introduction to Engineering Design. Density. Density. is a measure of the . amount of matter per unit of volume . Objects . more dense . than water . sink. Objects . less dense . than water . float. 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.. Introduction to Engineering Design. The International System of Units (SI). The International System of Units (SI) is a system of units of measurement consisting of seven base units. The abbreviation SI is from the French “. !
