8 degrees Celsius = 46.40°F (281.15 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 8°C: (8 × 1.8) + 32 = 46.40°F.

Here are three everyday situations where knowing that 8°C = 46.40°F makes a practical difference.
If a recipe involves simmering, fermenting, or proofing at 8°C, that's 46.40°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.
You're checking the weather for a trip abroad and the forecast shows 8°C. That's 46.40°F. A warm jacket and layers will keep you comfortable. Most weather apps let you switch between °C and °F, but knowing the conversion helps when reading local signage or talking to locals.
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. 8°C = 46.40°F = 281.15 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.
