Question

Convert 4.5 x 10^6 kilometers to micro meters

Answer 1

Convert $4.5 \times 10^{6}$ kilometers to micrometers.

Solution:

$$1 \, km = 10^{3} \, m$$ $$1 \, \mu m \, (\text{micrometer}) = 10^{-6} \, m$$

Thus:

$$4.5 * 10^{6} \, km = 4.5 * 10^{6} * 10^{3} \, m = 4.5 * 10^{6} * 10^{3} * 10^{-6} \, \mu m = 4.5 * 10^{15} \, \mu m$$

Answer: $4.5 * 10^{15}$ micrometers
