$1$ millimolar = $1 \times {10}^{- 3}$ molars

#### Explanation:

One molar contains 1,000 millimolars. You can convert molar to millimolar by multiplying the figure by 1,000. In the metric system, the prefix "milli-" represents 10 to the power of -3, or one one-thousandth.

So 1,000 millimolars = 1 molar. In scientific notation,

$1 \times {10}^{3}$ millimolars = 1 molar

So, multiplying both sides by ${10}^{- 3}$ gives

$1$ millimolar = $1 \times {10}^{- 3}$ molars
