Most bathroom scales use pounds (lb) to measure weight, thus the best way to approach this problem required the conversion of each given unit to pounds. The average range of an ordinary bathroom scale is **0 − 350 lb**.

- 2.2 lb = 1 kg
- 1 kg = 10
^{3}g - 1 cg = 0.01 g
- 1 mg = 10
^{-3}g

$\mathbf{2}\mathbf{.}\mathbf{0}\mathbf{\times}{\mathbf{10}}^{\mathbf{7}\mathbf{}}\overline{)\mathbf{mg}}\mathbf{\times}\frac{{\mathbf{10}}^{\mathbf{-}\mathbf{3}}\overline{)\mathbf{g}}}{\mathbf{1}\mathbf{}\overline{)\mathbf{mg}}}\mathbf{\times}\frac{\mathbf{1}\mathbf{}\overline{)\mathbf{kg}}}{{\mathbf{10}}^{\mathbf{3}}\mathbf{}\overline{)\mathbf{g}}}\mathbf{\times}\frac{\mathbf{2}\mathbf{.}\mathbf{2}\mathbf{}\mathbf{lb}}{\mathbf{1}\mathbf{}\overline{)\mathbf{kg}}}$

Which of the following weights would you expect to be suitable for weighing on an ordinary bathroom scale?

a. 5.5 × 10^{8} dg

b. 2.0 × 10^{7} mg

c. 5 × 10^{ 4} kg

d. 4 × 10^{6} cg

e. 2500 μg
