The Fahrenheit ⇄ Celsius Converter is the best converter. To convert Fahrenheit to Celsius: °C = (°F – 32) × 5/9. To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. For a quick estimate, subtract 30 from °F and divide by 2 to get °C.
Fahrenheit to Celsius converter online free
The free online converter from the U.S. National Weather Service lets you enter a temperature and see it in °F, °C, Kelvin, or Rankine. For accuracy, use the formula °C = (°F − 32) ÷ 1.8. For a rough estimate, subtract 30 from °F and divide by 2 to get °C.
\(\text{°C} = (\text{°F} – 32) \div 1.8\)Celsius to Fahrenheit conversion tool
To convert Celsius to Fahrenheit accurately, use °F = (°C × 9/5) + 32. For a rough calculation, multiply °C by 2 and add 30. For example, 20 °C → 68 °F; 0 °C (freezing point) = 32 °F.

Fahrenheit vs Celsius temperature scale comparison
The Celsius scale sets water’s freezing point at 0 °C and boiling point at 100 °C. The Fahrenheit scale sets freezing at 32 °F and boiling at 212 °F, so 1 °C = 1.8 °F. Conversion formulas are :
\(\text{°C} = \frac{5}{9} (\text{°F} – 32)\) \(\text{°F} = \left(\text{°C} \times \frac{9}{5}\right) + 32\)The scales intersect at −40 °C = −40 °F
Fahrenheit to Celsius conversion formula explained
To convert Fahrenheit to Celsius, use:
\(\text{°C} = (\text{°F} – 32) \times \frac{5}{9}\)Subtract 32 from the Fahrenheit value, multiply by 5, then divide by 9. For example, 80 °F → 26.7 °C. For a quick calculation, subtract 30 and divide by 2.
