Which of the following is not the same as 12.5 millimeters? 0.125 km 0.00125 hm 0.0125 m 1.25 cm

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.

0.00125 hm

Hope this helps!
