15. Units of Measurements Mass = Length = Volume = Temperature * Standard unit = kilogram Grams (g) Meters (m) Liters (l) * Celcius (*C)

16. Metric System Kilo Hecto Deka g, l, m, s Deci Centi Milli 1000 100 10 1 (10) (100) (1000) (k~) (h~) (da~) g, l, m, s (d~) (c~) (m~) (Larger than 1) “” 1 (1/10) (1/100) (1/1000)

18. What is the difference between mass and weight? Mass is the amount of matter. Weight is the force of gravity pulling on that matter.
