You can check current weather conditions with Siri by asking Siri to check the weather, like “What’s the weather today?” or “How’s the weather in Chicago right now?”. Siri will tell you the temperature either in fahrenheit (symbol °F) or in celsius (symbol °C – centigrade). You can change this setting easily. Here is how:
1. Open the Weather app on your iPad, iPod or iPhone
2. Tap the “i” information icon
3. From here, you may tap to select the units of measure (°F or °C) that you prefer for your weather data that Siri reports and then tap Done.
