Metric+System+Notes

__Metric System Notes__ (Cornell Style, Sci Notebook) Different kinds of measurements have different kinds of base units. Length = meter Volume = liter Mass = gram __Temperature__ = Celsius degrees __Length__ = the distance between two points; the longest dimension of an object __Volume__ = the amount of space taken up by something __Mass__ = the amount of matter an object has

1. Prefixes plus base units make up the metric system. Example: kilometer or kilogram

2. The most used prefixes are: kilo, centi, milli

3. These prefixes are based on powers of 10

4. From each prefix every “step” is either: 10 times larger or 10 times smaller

5. The prefix list. (Numbers are values compared to the base-unit.)
 * Kilo- ||  || Hecto- ||   || Deka- ||   || Base ||   || Deci- ||   || Centi- ||   || Milli- ||
 * k ||  || h ||   || da ||   || Unit ||   || d ||   || c ||   || m ||
 * 1000 ||  || 100 ||   || 10 ||   || 1 ||   || 0.1 ||   || 0.01 ||   || 0.001 ||

6. (Write one of the following to remember how to write the prefix list in order.) King Henry Drank Milk During Castle Meetings King Henry Doesn’t Usually Drink Chocolate Milk K ing H enry D ied B y D rinking C hocolate M ilk

7. Converting Step 1: A list of the decimal prefixes or units written in the correct order can be use to convert between metric units.

8. Step 2: First find the unit you are converting from and the unit you are converting to in the list.

9. Step 3: Next, count the spaces between these prefixes in the list. Starting at the prefix your are converting from and move towards the prefix you are converting to.

10. Step4: Then, move the decimal in the number you are converting the same direction that you counted in the list and one place for every space you counted.

Practice: Convert the following: 75 cm = .......... m 1000 m = .......km 0.001 hg = ........ dg 42.7 L = .............cL .......................................................................................................................  Example Summary Base units in the metric system are meter, liter, gram Length = distance between points Volume = space occupied by something Mass = matter in an object Metric system is based on powers of 10 For conversions within the metric system, each “step” is 1 decimal place to the right or left Using the diagram below, converting to the right, moves the decimal to the right and vice versa Kilo- Hecto- Deca- Meter Deci- Centi- Milli-
