The freezing point for water and many foods is 32º Fahrenheit, so you might think that your freezer would be safe set around there. The ideal temperature for freezers is 0º Fahrenheit.
The correct temperature for your freezer is 0 degrees Fahrenheit—if you set it to 0 degrees (-18 degrees Celsius) and keep it fairly full, it will maintain that temperature. How to Monitor ...

Temperature settings for refrigerator and freezer compartments are often given arbitrary numbers by manufacturers (for example, 1 through 9, warmest to coldest), but generally 3 to 5 °C (37 to 41 °F) [3] is ideal for the refrigerator compartment and −18 °C (0 °F) for the freezer. Some refrigerators must be within certain external ...
On inquiring about the temperature at which paper would catch fire, Bradbury had been told that 451 °F (233 °C) was the autoignition temperature of paper. [ 30 ] [ 31 ] In various studies, scientists have placed the autoignition temperature at a range of temperatures between 424 and 475 °F (218 and 246 °C), depending on the type of paper.
A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...
Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = 9 / 5 {ΔT} °C.
