A balloon is blown up so that its volume is 1,500 mL. What is its volume in kL?

$1.5 \times {10}^{-} 3 \cdot k L$

Explanation:

$1500 \cdot m L = 1500 \times {10}^{-} 3 L$

$=$ $1500 \times {10}^{-} 3 \cancel{L} \times {10}^{-} 3 \cdot k L \cdot \cancel{{L}^{-} 1}$

$=$ $1500 \times {10}^{-} 6 \cdot k L$

$=$ $1.5 \times {10}^{-} 3 \cdot k L$

Note that $1 \cdot k L \equiv 1 \cdot {m}^{3}$.
