How many meters would 5446 cm convert? (Must show work on your paper worked out). 1.  Ask yourself, are you converting meters (bigger or smaller) than centimeters.  Then ask if you are going "big to small units" or "small to big units"? 2. Then ask, what does centi- prefix mean and how many zeros are in the unit (1 meter=100 centimeters)   READ BELOW BEFORE YOU ANSWER: *Simply convert to "SMALLER" unit by moving the decimal point to the "right" or "multiply". *Simply convert to "LARGER" unit by moving the decimal point to the "left" or "dividing".  For example, let's say a friend told you that he weighed 72,500.0 grams (159.5 lbs), you can convert this to kilograms simply by moving the decimal three places to the left or dividing; in other words, your friend weighs 72.5 kilograms.  (smaller units are (grams)  to bigger units (kilograms)-72,500 divided by 1000=72.5 Which way do you know to move decimal, left or right?    This depends on if you convert:         -grams to kilograms = smaller to larger = move left.        - centimeter to meter         -millimeter to centimeter                              OR                  -kiograms to grams = larger to smaller = move right.        -centimeter to millimeter        - liter to millimeters   How do you know how many places to move the decimal?    -Move decimal 3 place to left because there are 3 zeros in       kilo- means -1000 and you are going from small to big.     -centi- means-100 = 2 places   1 kilometer = 1,000 meters- 1 meter = 100 centimeters  1 centimeter = 10 millimeters This system is based on the decimal system and base units of 10s.      1. Count the number of zeros in the             number you are multiplying or dividing         by. 2. If you are multiplying, move the decimal point this number of places to the right. 3. If you are dividing, move the decimal point this number of place to the left.
