Lettuce retains quality and nutrition best if kept refrigerated. Minimally processed lettuce should be treated like any other potentially hazardous food and should be kept refrigerated.
5 degrees is colder
-5 degrees Fahrenheit = -20.5 degrees Celsius.
5 °C - 10 °C = -5 °C (i.e. 5 degrees Celsius below 0 °C or 5 °C below freezing)
it all depends on what scale. 0 degrees Kelvin (K) is the ultimate lowest temperature possible. In Celsius it is -273,15 and it can't get any lower. So 5 degrees below zero is not below 0 K. When you Celsius as scale it means it is 5 degrees below the point that water freezes.

95 degrees Celsius is five degrees below the boiling point of water. If you are working in Fahrenheit it is 207 degrees Fahrenheit.
5
below 5 degrees
-5
It's probably 5 or even 10 degrees below 0 degrees in Fahrenheit.
To convert between degrees Celsius and degrees Fahrenheit, take the number, multiply it by 9, divide it by 5, and add 32. To use an example below freezing, -5 x 9 = -45 / 5 = -9 + 32 = 21 degrees Fahrenheit.
