Example:
Suppose a plot is measured to be 70 square feet.
You are asked to find the area in square meters.
The solution requires using three conversion multipliers each used twice:
,
, and
.
This can be written as
(\frac{2.54^2cm^2}{in^2})(\frac{1m^2}{100^2cm^2})=6.5032...m^2)
Note how ft
2, in
2, and cm
2 cancel in the conversions.
To solve this using the graphing calculator below,
enter 70(12^2)(2.54^2)/(100^2) into the
Function f(x) = box.
Then click on the
Plot Graph button.
The answer is displayed below the Function f(x)=box as f(x)= 6.5032... .
