To convert the average rainfall in London from millimeters (mm) to meters (m), you note that 1 meter is equal to 1,000 millimeters.

Given that the average rainfall is 557 mm:

$$\text{Rainfall in meters}=\frac{557\text{ mm}}{1000}=0.557\text{ m}$$

So the average rainfall in London each year is 0.557 meters.
