CONVERTING HIGHER TO LOWER UNITS: If the unit becomes smaller, the value gets larger. So, the decimal place moves to the right. (Multiply by units of 10) Centi c Milli m How many centmeters are in 1.98 meters? What unit are you starting with? What unit do you want to convert
to? METRIC CHEATER CHART CONVERTING LOWER TO HIGHER UNITS: If the unit becomes larger, the value become smaller. So, the decimal place moves to the left. (Divide by units of 10) Kilo k Hecto h Deka

CONVERTING HIGHER TO LOWER UNITS: If the unit becomes smaller, the value gets larger. So, the decimal place moves to the right. (Multiply by units of 10) Centi c Milli m 75 cm = 7.5 dm 75 cm = .75 m Volume
The amount of space occupied by an object. Length x Width x Height Units = cubic. Cubic centimeters = cm3
Cubic meters = m3 Liquid volume Liter QuickTime and a decompressor are needed to see this picture. Derived Units Units that are made by combining other SI
units Meter x Meter x Meter = M3 Mass The amount of matter in an object. SI unit = kg Use a balance to measure mass. Density
The mass per unit volume of a material. Density is a derived unit. Mass/volume g/cm3 Time
The interval between two events SI unit = seconds (s) QuickTime and a decompressor are needed to see this picture. Temperature Measured with thermometer Celsius scale
Freezing point of water = 00C Boiling point of water = 1000C SI unit = Kelvin Absolute zero = 273 K = -2730C Ch. 2.2 Graphing Graphing (p.48-51) Types
of graphs What are graphs used for? To display information or data Can be used to visually compare data Different types of graphs are used to display different types of data.
Line Graph shows the relationship between 2 variables Change over time Dependent Variable A. Types of Graphs
Independent Variable A. Types of Graphs Bar Graph shows information collected by counting A. Types of Graphs
Pie Graph shows distribution of parts within a whole quantity
