Celsius to Fahrenheit Formula

°F = °C × 9/5 + 32 The reverse direction: °C = (°F − 32) × 5/9 Both are exact. There's no rounding built into the formula itself, only in how many decimal places a result is displayed.

Common Celsius to Fahrenheit Conversions

0°C = 32°F (freezing point of water) 20°C = 68°F (room temperature) 25°C = 77°F 37°C = 98.6°F (normal body temperature) 100°C = 212°F (boiling point of water)

How to Convert Celsius to Fahrenheit

Multiply the Celsius value by 9, divide by 5, then add 32. For example, converting 20°C: 20 × 9 = 180, 180 ÷ 5 = 36, 36 + 32 = 68°F. Going the other way, from Fahrenheit to Celsius: subtract 32 first, then multiply by 5 and divide by 9.

Celsius to Fahrenheit Examples

Converting a UK oven temperature of 180°C for a US recipe: 180 × 9/5 + 32 = 356°F. Checking if 98.6°F (average human body temperature) matches 37°C: (98.6 − 32) × 5/9 = 37°C. Correct. Converting a US weather forecast of 72°F to Celsius: (72 − 32) × 5/9 = 22.2°C.

FAQs

Frequently Asked Questions

Common questions about Celsius to Fahrenheit Converter.

°F = °C × 9/5 + 32, and the reverse: °C = (°F − 32) × 5/9. Standard, exact, no approximation.

0°C (freezing point of water) equals exactly 32°F, so those are shown as the starting values you can edit from.

Double the Celsius value and add 30 for a rough estimate, e.g. 20°C × 2 + 30 = 70°F, versus the exact 68°F. Not precise, but close enough for a quick weather check.

98.6°F is just the exact conversion of 37°C using the standard formula; it only looks precise because Fahrenheit's scale happens to produce a non-round number for that particular Celsius value. Modern guidance also treats average body temperature as a range rather than one fixed figure, but 37°C/98.6°F remains the commonly cited reference point.
