Conversion formula
How to convert 105 kilometers to millimeters?

We know (by definition) that: $1 km = 1000000 mm$

We can set up a proportion to solve for the number of millimeters.

\frac{1 km}{105 km} = \frac{1000000 mm}{x mm}

Now, we cross multiply to solve for our unknown $x$ :

x mm = \frac{105 km}{1 km} * 1000000 mm \to x mm = 105000000 mm

Conclusion: $105 km = 105000000 mm$

105 kilometers is equivalent to 105000000 millimeters
