Unit Conversions And Factor Label Method Math
In an attempt to prepare students for units analysis in the solution of problems in high school chemistry and physics the author developed learning packets on the factor label method.
Unit conversions and factor label method math. Metric units of mass review g and kg our mission is to provide a free world class education to anyone anywhere. Thirty three students used these packets individually during a regular tenth grade geometry class. The resulting unit is quarts. The useful aspect of converting units or dimensional analysis is in doing non standard conversions.
Dennis didn t quite make it to six hundred but this unit conversion did kill some time for the bedraggled mother. Multiply the given measurement by the conversion factor. Factor label method and dimensional analysis commonly used in one step and two step unit conversions for chemistry physics math and science. There were two packets each to be used for two days.
Write the conversion as a fraction that equals 1. Metric units of mass review g and kg up next. While you can find many standard conversion factors such as quarts to pints or tablespoons to fluid ounces life and chemistry and physics classes will throw you curve balls. Dimensional analysis also called factor label method or the unit factor method is a problem solving method that uses the fact that any number or expression can be multiplied by one without changing its value.
Math skills dimensional analysis. In the egg problem the statement that 1 dozen eggs 12 eggs is a conversion factor. Math 5th grade converting units of measure. A conversion factor is a statement of the equal relationship between two units.
Today in lab we will investigate several examples of unit conversion using a process called the factor label method. Let s start with a simple example. Khan academy is a 501 c 3 nonprofit organization. The first step in dimensional analysis is therefore identifying the conversion factor s you will need to make your conversion.
This is a technique that will be used with regularity in this and other science courses. Convert 3 km to m 3 kilometers to meters. There are 1000 m in 1 km so the conversion is easy but let s follow a system.
