The most important goal for the adult learner
is to be able to use and apply the skill of
converting within the metric system that is
learned in an academic setting and be able to
apply it to real-life situations.
The decimal measuring system based on the meter, liter,
and gram as units of length, capacity, and weight or
mass
The metric system is in use by 95% of the world
The metric system is universally used in the sciences
The only country in the world that does not utilize the
metric system is the United States
There are three basic units of metric measure
that the adult learner will use in real-life
situations:
meter (m) - length
gram (g) - mass or weight
liter (L) - volume
Many disciplines use the metric system, such as
pharmacology, chemistry, nursing and
astronomy. For example, the average distance
between the moon and the earth is 384,403
kilometers (238,857 miles). When nurses
calculate how much an infant takes from a
bottle, they do it in cubic centimeters. Thirty cc's
equals about an ounce.

How do you use the “ladder” method?
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of
jumps in the same direction.

An easy way to remember the metric units of
measure is to remember the sentence:
King Henry died ___ drinking chocolate milk!
(Poor guy!!!)
kilo- (1000)
hecto- (100)
deka- (10)
deci- (0.1)
centi- (0.01)
milli- (0.001)
