k=kilo
d= deci
h=hector
c=centi
da=deca
m=milli
Base unit= m for meter, g for grams, l for
liter, etc
To use the Stair-Step method,
•
find the prefix the original measurement starts with. (ex. milligram) If there is no prefix,
then you are starting with a base unit.
• Find the step which you wish to make the conversion to. (ex. decigram)
• Count the number of steps you moved, and determine in which direction you moved (left
or right).
• Move your decimal place the number of steps that you moved in the direction you moved
(ex. milligram to decigram is 2 steps to the left, so 40 milligrams = .40 decigrams) If the number
of steps you move is larger than the number you have, you will have to add zeros to hold the
places. (ex. kilometers to meters is three steps to the right, so 10 kilometers would be equal to
10,000 m
That’s all there is to it! You need to be able to count to 6, and know your left from your right!
