1 The Metric SystemObjective: Identifying what units are used for different measurements and how to convert measurements.
2 International System of Units International System of Units (SI)Seven units of measurement known as the basic set which other units are derived from
3 International System of Units Unit SymbolsSymbols used to define a number based on what is being measuredLength = meter (m)Mass = kilogram (kg)Force = newton (N)Time = second (s)Area = square meters (m2)Volume = cubic meters (m3)Density = grams per centimeters cubed(g/cm3)Temperature = kelvin (K)
4 Conversions Temperature Conversion °F to °C = 5/9(°F - 32 °) °C to °F = 9/5(°C) + 32 °°C to K = °CExample 1: Convert 32 °F to °C.Example 2: Convert 29 °C to K.
5 Conversions Steps: Find the prefix. (beginning of the word) kilohectodekaBase UnitdecicentimilliSteps:Find the prefix. (beginning of the word)Find out what you are converting to.Count the number of stairs you need to move.What direction did you move in?Move the decimal point the same to same number of stairs and the same direction of motion.
6 Conversion Example 1: Convert 45 centimeters into meters. kilohectodekaBase UnitdecicentimilliExample 1: Convert 45 centimeters into meters.Example 2: Convert 9 kilometers into decimeters
7 CalculationsDensityThe amount of mass (g) in a given volume (cm3) of an objectDensity = mass / volumeHigh Density = SinkLow Density = FloatWater has a density of 1g/cm3
