    Exercise \(\PageIndex{1a}\)

    Perform the following unit conversion.

    12 g = _________ lb.

    Answer

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

    Exercise \(\PageIndex{1b}\)

    Perform the following unit conversion.

    67.3 km = _________ mm

    Answer

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

    Exercise \(\PageIndex{1c}\)

    Perform the following unit conversion.

    39.3 in. = _________ cm

    Answer

    \(39.3 \ in. \ x \ \dfrac {2.54 \ cm} {1 \ in.} \ = 99.8 \ cm\)

    Exercise \(\PageIndex{1d}\)

    Perform the following unit conversion.

    60.0 cal = __________ J

    Answer

    \(60.0 \ cal \ x \ \dfrac {4.184 \ J} {1 \ cal} \ = \ 251 \ J \)

    Exercise \(\PageIndex{1e}\)

    Perform the following unit conversion.

    1.2 x 10-9 mg = ________ μg

    Answer

    \( 11.2 \ x \ 10^ {-9} \ mg \ x \ \dfrac {1 \ g} {1000 \ mg} \ x \ \dfrac {10^ {6} \ μg} {1 \ g} \ = 1.2 x 10^ {-6} \ μg \)
