How to convert 201 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.

1 km / 201 km = 1000000 mm / x mm

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

x mm = (201 km / 1 km) * 1000000 mm → x mm = 201000000 mm

Conclusion:

201 km = 201000000 mm
