Conversion formula
°C = ((°F × (5 / 9)) + (45,967 / 180) × (1)) − (273.15)70 °F ≈ 21.1111 °C
degree Fahrenheit (°F)
Fahrenheit uses °C = (°F − 32) × 5/9; 32 °F = 0 °C and 212 °F = 100 °C.

degree Celsius (°C)
The Celsius scale has the same interval as kelvin, with 0 °C = 273.15 K; water freezes near 0 °C at standard pressure.

Frequently asked questions
How many degrees Celsius are in 70 degrees Fahrenheit?
70 °F ≈ 21.11 °C. °C = ((°F × (5 / 9)) + (45,967 / 180) × (1)) − (273.15)
How do I convert °F to °C?
°C = ((°F × (5 / 9)) + (45,967 / 180) × (1)) − (273.15)
Why does this conversion need more than multiplication?
Temperature scales have different zero points. Apply the scale and offset in the formula; below absolute zero is a mathematical result only.
