Conversion formula
How to convert 20 kilometers to centimeters?

We know (by definition) that: 1 km = 100000 cm.

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

1 km / 20 km = 100000 cm / x cm

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

x cm = (20 km / 1 km) * 100000 cm x cm = 2000000 cm

Conclusion:

20 km = 2000000 cm


Conversion in the opposite direction

The inverse of the conversion factor is that 1 centimeter is equal to 5e-07 times 20 kilometers.

It can also be expressed as: 20 kilometers is equal to 1 / 5e-07 centimeters.


Approximation

An approximate numerical result would be: twenty kilometers is about two million centimeters, or alternatively, a centimeter is about zero times twenty kilometers.
