Answer:
The factor-label method is a problem solving technique using units (labels) and conversion factors. Units tell
us the type of measurement being made; for example, "5.2 cm" has a unit (cm) which tells us the measurement
to be made is length. Conversion factors (also known as "equalities") are fractions that relate two kinds of
units; for example, "6.0 cm / s" tells us that for every 1 second that passes (time), 6.0 cm are covered (length).
Notice that "6.0 cm s-1" is the same as "6.0 cm / s" in unit notation.
- Numbers and units are considered separately.
- Multiply by as many conversion factors as necessary.
- Common conversion factors may or may not be supplied with the problem.
