What temperature does freeze at?

What Temperature Is Freezing? Water will freeze at 0 degrees Celsius, which is 32 degrees Fahrenheit. Any time the temperature drops below these, liquid water will begin to turn into ice. Water behaves very differently than other liquids.

What happens if your freezer is too cold?

However, if your freezer is running too cold or there's a fluctuation in temperature, this may cause freezer burn. Check for ice crystals on the outside of food. While food with freezer burn is usually safe to eat, the food's flavor and texture may be compromised.

What temp should a true freezer be at?

Freezers, on the other hand, are designed to keep food frozen and stop the growth of bacteria. This is why it is important to make sure your freezer is set to the correct temperature of 0°F / -18°C.
