Which measurement below represents the heaviest mass? which measurement below represents the heaviest mass? 1 mg 1 kg 1 pg 1 mg 1 dg?

            1 Kg

Explanation:

Let us convert all given masses into Kg and compare it with 1 Kg.

1) 1 mg;

                   1 mg  =  1.0 × 10⁻⁶ Kg

Hence it is far more lighter than 1 Kg.

2) 1 pg;

                   1 pg  =  1.0 × 10⁻¹⁵ Kg

Hence it is also far more lighter than 1 Kg.

3) 1 dg;

                   1 dg  =  1.0 × 10⁻⁴ Kg

Hence it is also far more lighter than 1 Kg.
