1 mm (millimeter) = 0.000001 km (kilometer)
12.5 mm = 0.0000125 km
1 mm = 0.00001 hm (hectometer)
12.5 mm = 0.000125 hm
1 mm = 0.001 m (meter)
12.5 mm = 0.0125 m
1 mm = 0.1 cm (centimeter)
12.5 mm = 1.25 cm
So the only one of the answer choices that doesn't equal 12.5 mm is 0.00125 hm, since 12.5 mm is 0.000125 hm.
Answer:
0.00125 hm
Hope this helps!
