Temperature around 0°C How to say that the lowest temperature will be around 0°C (e.g. -1°C ~ 1°C)?

My attempt is:


  最低气温会成0°C左右。
As fefe has mentioned, you could use “在”…左右&thinsp;/上下/&thinsp;附近 to describe a range near some position, somewhat like describing locations.


  最低氣溫在 0 度左右；
  蛋白質凝固的溫度在 65 度上下。


It is not needed for exact values.


  現在室溫 7 度；
  冷凍室的溫度是 -20 度。


For estimated values, you may also use 約 (about) to indicate uncertainty.


  最低溫約為零度。


It is worth noting that Celsius is omitted in all examples above, since Celsius is usually the only tempreture scale employed. Other scales, such as Fahrenheit and Kelvin, only exist in special contexts like academic research. You may use …°C (pronounced “度 C”) or 攝氏…度 if explicitness is needed.

Here is an example video for daily usages. In this weather forecast (YouTube video) of Next TV, Taiwan, the reporter uses 


  白天最高溫降到只有 24 度左右。


to express the tempreture lowers to tempretures near 24°C. 

Sidenote:
Please note that she also uses 


  最低溫下探 17 度。


to indicate the lowest temperature would touch a lower bound of 17°C. This is mainly used in Taiwan for weather and stock reports. It is not used in China and usually would be interpreted as lower by 17 degrees rather than lower to 17°C.
