centimeters.
Conversion
Factor(s):
1 m = 100 cm
3 Step Solution:
1. Start with the given, in
this example it’s 5 m.
2. Use the conversion factor
and make a fraction from
it such that it cancels out
the known unit.
3. Cancel out numbers and
units to get the unknown.
You can make two fractions from the
conversion factor (1m = 100cm).
1m
100 cm
OR
100 cm
1m
Our aim is to cancel out the meters
and retain the Cm in the final answer.
So setup the problem by using the
second fraction.
