Exercise $$\PageIndex{1a}$$

Perform the following unit conversion.

12 g = _________ lb.

$$12 \ g \ x \ \dfrac {1 \ lb.} {453.6 \ g} \ = \ 0.026 \ lb.$$

Exercise $$\PageIndex{1b}$$

Perform the following unit conversion.

67.3 km = _________ mm

$$67.3 \ km \ x \dfrac {1000 \ m} {1 \ km } \ x \dfrac {1000 \ mm} {1 \ m} \ = \ 6.73x 10 ^ {7} \ mm$$

Exercise $$\PageIndex{1c}$$
