You Can Change Precipitation Units Now

Before iOS 18, precipitation was always represented in your default country’s unit of measure: inches in the US and millimeters in Canada, for example. This meant that you could only check the precipitation for snow or rain in that unit of measurement.

Granted, that’s fine for most people as that’s the standard in their country. However, some prefer to use alternative units of measurement for weather. Luckily, iOS 18 now lets you change this to whichever you prefer.

To change it, you need to do the following:

1. Open the Weather app.
2. If you’re in a location, swipe down to your list of locations. 
3. Tap the three-dot button in the top right corner.
4. Go to Units.
5. Tap on Inches next to Precipitation. 
6. Select Milimiters and centimiters (mm, cm).

And that’s it. Now, to check for rain and snow in the precipitation chart, you need to go back to a location and tap on the weather conditions right below the temperature.

Now, scroll down, and under Precipitation totals, you’ll see the rain and snow in millimeters or centimeters.
