SI Units Scientists use a standard set of units for all measurements The SI Units Same as the Metric System What you are measuring Unit Symbol Length meter m Mass gram g Temperature Celcius C Time second s Volume liter L end

SI Unit Prefixes When you make a measurement, you need to use the right unit Would you measure a classroom in feet or miles? SI Units allow us to convert by moving decimals and adding prefixes. end

SI Unit Prefixes With the SI units you can convert between small and large measurements using: King Henry Died By Drinking Chocolate Milk end

SI Unit Prefixes King Henry Died By Milk Kilo Hecto Deca Deci Centi Drinking Chocolate Milk Kilo Hecto Deca Deci Centi Milli k h da d c m To convert between prefixes: Use the chart above to find your first prefix. Use the chart above to find your final prefix. Count the number of times you move your decimal Move the decimal in that direction the same number of places If there is only 1 letter, then you are at the Base Unit end end

SI Unit Prefixes 35 mL = ___ L 12 g = ___ mg 25 cm = ___ mm 4 L = ___ daL 4500 mg = ___ g 0.07 m = ___cm end

Temperature There are 3 scales used to measure temperature Fahrenheit (°F): Used in the U.S. Celsius (°C): Used in all other countries in the world Kelvin (K): Used by scientists To convert between them, use the following: end

Temperature Convert the following temperatures: 26 °C = _____ °F 98 °F = _____ °C 34 °C = _____ K 901 °C = _____ °F 60 °C = _____ K end

Temperature Temperatures you should know: °F °C K Water Boils 212 100 373 Human Body 98.6 37 310 Room Temp 68 20 293 Water Freezes 32 273 end
