Frequently asked questions
How do I convert Celsius to Fahrenheit?
Use the formula °F = (°C × 9/5) + 32. Multiply the Celsius temperature by 1.8, then add 32. For example, 20°C = (20 × 1.8) + 32 = 68°F.
What temperature is the same in Celsius and Fahrenheit?
−40°. At −40 degrees both scales read the same number, because (−40 × 9/5) + 32 = −40. It is the only point where Celsius and Fahrenheit intersect.
What is 0°C in Fahrenheit?
0°C is 32°F — the freezing point of water. And 100°C (boiling water) is 212°F.
What is 18°C in Fahrenheit?
18°C equals 64.4°F ((18 × 1.8) + 32 = 64.4). See our dedicated 18 Celsius to Fahrenheit page for more detail.
