−50 degrees Celsius = -58.00°F (223.15 K). Use the copy buttons below for any format, or enter a custom value in the converter.
The Celsius scale sets 0°C at the freezing point of water and 100°C at its boiling point. The Fahrenheit scale, used primarily in the United States, sets those same points at 32°F and 212°F. To convert Celsius to Fahrenheit, multiply by 9/5 and add 32: °F = (°C × 9/5) + 32. For −50°C: (-50 × 1.8) + 32 = -58.00°F.

Extreme polar cold
−50°C is dangerously cold — recorded in the interior of Antarctica and parts of Siberia. At this temperature, exposed skin can suffer frostbite in under a minute, and diesel fuel gels without additives.

Here are three everyday situations where knowing that −50°C = -58.00°F makes a practical difference.
If a recipe involves simmering, fermenting, or proofing at -50°C, that's -58.00°F. For example, bread dough proofing at 25–30°C, chocolate tempering at 31–32°C, and sous-vide cooking at 55–65°C all require precise Celsius-to-Fahrenheit conversions when using US kitchen tools.
-50°C (-58.00°F) is outside typical everyday weather ranges — you'd encounter this in extreme environments, industrial settings, or science experiments rather than a weather forecast.
In a chemistry or physics class, temperatures are often given in Celsius and need to be converted for US-format worksheets, or converted to Kelvin for thermodynamics problems. -50°C = -58.00°F = 223.15 K. The Kelvin scale is used in the ideal gas law (PV = nRT) and other thermodynamic equations where absolute zero (0 K = −273.15°C) is the reference point.
