Conversion formula
How to convert 40 meters to millimeters?

We know (by definition) that: 1 m = 1000 mm.

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

1 m / 40 m = 1000 mm / x mm

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

x mm = (40 m / 1 m) * 1000 mm → x mm = 40000 mm

Conclusion:

40 m = 40000 mm
