2. What is the Metric System?Aka. S.I. System (International Standards) A tool for measurement of different valuesVery consistent unit of measurementFor Example:LengthMassVolumeTime
3. Common Metric Units Table Quantity Base Unit Symbol Length meter mMass gram g Volume liters m3 (cubic meter)Time second tForce Newton NTemperature Celsius C or K (Kelvins)
4. Metric PrefixA prefix is added to a base unit to indicate the multiplication factor for that value. The multiplication factors are always powers of 10Over 20 different prefixes Common prefixes:Mega, Kilo, Centi, Mili, Micro, and Nano

7. Domino Method Part 1
8. Domino MethodHelpful when converting between units.Rule of Thumb: The top of the "domino" is the numeratorThe bottom is the denominatorThe horizontal line is one long fraction bar (or division sign)
9. 3 Steps for Dominos 1) Place the amount and units that are going to be converted 2) Put the conversion factors (i.e. between English and Metric units) 3) Calculate by multiplying values on the top and dividing by values on the bottom.
