10 Metrics

11 Label the larger of the two MilliCenti HectoDeca DecaDeci MeterLiter

12 Metrics, Estimate 150 Meters = ____ Yards 20 Inches = _____ Meter 20 Feet = _____ Meters 1 Meter = _____ Feet 2000 Millimeters = ____ Meters

13 Metrics, Why Why can metrics be an easier standard of measurement? Because it is based on 10s Because it is consistent between weight, length, and volume Where in the world is metrics used? Where is the standard system used? Metrics- Europe / Rest of world Standard- United States

14 Temperature, Conversions 0 Fahrenheit = ____Celsius 0 Celsius = ____Fahrenheit 0 Kelvin = _____ Fahrenheit 37 Celsius = _____Fahrenheit 50 Fahrenheit =_____Celsius 25 Celsius = ____ Fahrenheit
