    The answer is: C. 0.00427 m.

    A) 1 km = 1000000 mm.

    d = 0.0000427 km · 1000000 mm/km.

    d = 47.7 mm.

    B) 1 hm = 100000 mm.

    d = 0.000427 hm · 100000 mm/hm.

    d = 42.7 mm.

    C) 1 m = 1000 mm.

    d = 0.00427 m · 1000 mm/m.

    d = 4.27 mm.

    D) 1 cm = 10 mm.

    d = 4.27 cm · 10 mm/cm.

    d = 42.7 mm.

    Millimeter (abbreviated: mm, a thousandth part of metar) is an unit of distance in the metric system.
