Theo mặc định, Weather API trả về dữ liệu theo hệ đo lường. Để yêu cầu dữ liệu thời tiết bằng hệ thống đo lường Anh, hãy chỉ định tham số unitsSystem trong yêu cầu của bạn.
Ví dụ sau đây yêu cầu dữ liệu thời tiết cho Mountain View, California theo đơn vị đo lường của Anh:
curl -X GET "https://weather.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY&location.latitude=37.4220&location.longitude=-122.0841&unitsSystem=IMPERIAL"
