What Is a Fahrenheit to Celsius Converter and How Does It Work?

A Fahrenheit to Celsius converter applies a simple mathematical formula to translate temperatures between the two most commonly used scales worldwide. The US uses Fahrenheit (°F) for everyday weather and body temperature; most of the rest of the world uses Celsius (°C). This free Fahrenheit to Celsius converter works in both directions — enter °F to get °C, or enter °C to get °F. It also works as a full temperature converter with the formula shown so you can verify every result.

Fahrenheit to Celsius Formula — How to Convert F to C

The Fahrenheit to Celsius formula subtracts 32 from the °F value then multiplies by 5/9:

°C = (°F − 32) × 5/9Example — convert 98.6°F to Celsius: °C = (98.6 − 32) × 5/9 = 66.6 × 0.5556 = 37°CExample — convert 72°F to Celsius: °C = (72 − 32) × 5/9 = 40 × 0.5556 = 22.22°C

Celsius to Fahrenheit Formula — How to Convert C to F

The Celsius to Fahrenheit formula multiplies °C by 9/5 then adds 32:

°F = (°C × 9/5) + 32Example — convert 37°C to Fahrenheit: °F = (37 × 1.8) + 32 = 66.6 + 32 = 98.6°FExample — convert 100°C to Fahrenheit: °F = (100 × 1.8) + 32 = 180 + 32 = 212°F
💡 Quick mental shortcut to convert Fahrenheit to Celsius: Subtract 32 then halve the result. Example: 68°F → 68−32=36 → 36÷2=18°C. The exact answer is 20°C, so this approximation is within 2 degrees for most everyday temperatures. For precise conversion use the F to C converter above.

Fahrenheit to Celsius Converter — Frequently Asked Questions

What is the Fahrenheit to Celsius formula?
°C = (°F − 32) × 5/9. Subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or divide by 1.8). Example: convert 98°F to Celsius → (98 − 32) × 5/9 = 66 × 0.5556 = 36.67°C. The Fahrenheit to Celsius converter above shows the full formula for every conversion.
What is the Celsius to Fahrenheit formula?
°F = (°C × 9/5) + 32. Multiply the Celsius temperature by 9/5 (or 1.8), then add 32. Example: convert 37°C to Fahrenheit → (37 × 1.8) + 32 = 66.6 + 32 = 98.6°F. Switch to C to F mode in the temperature converter above to calculate celsius to fahrenheit instantly.
How do you convert Fahrenheit to Celsius without a calculator?
Quick approximation: subtract 32 from °F, then halve it. Example: 68°F → 68−32=36 → 36÷2=18°C (exact is 20°C, so within 2 degrees). For body temperatures, a more useful shortcut is to remember that 98.6°F = 37°C and 100.4°F = 38°C as anchor points. For exact results, use this F to C converter.
How do you calculate Celsius to Fahrenheit?
Multiply °C by 1.8 then add 32. Formula: °F = (°C × 1.8) + 32. Example: calculate celsius to fahrenheit for 20°C → (20 × 1.8) + 32 = 36 + 32 = 68°F. How do you convert celsius to fahrenheit for body temperature? 37°C × 1.8 + 32 = 98.6°F.
What is 98.6 Fahrenheit in Celsius?
98.6°F = 37°C. This is average normal human body temperature. Formula: (98.6 − 32) × 5/9 = 66.6 × 0.5556 = 37°C. Anything above 100.4°F (38°C) is considered a fever.
What is 100°F in Celsius?
100°F = 37.78°C. Formula: (100 − 32) × 5/9 = 68 × 0.5556 = 37.78°C. A temperature of 100°F in a person indicates a mild fever. The clinical fever threshold is 100.4°F (38°C).
What is 59°F in Celsius?
59°F = 15°C. Formula: (59 − 32) × 5/9 = 27 × 0.5556 = 15°C. This is a cool, mild temperature — typical of a spring or autumn day.
What is 36.6°C in Fahrenheit?
36.6°C = 97.88°F. Formula: (36.6 × 1.8) + 32 = 65.88 + 32 = 97.88°F. This is within the normal human body temperature range. Similarly, 36.3°C = 97.34°F.
What is 28°F in Celsius?
28°F = −2.22°C. Formula: (28 − 32) × 5/9 = −4 × 0.5556 = −2.22°C. This is below freezing — water will freeze at these temperatures.
What is 200°C in Fahrenheit for cooking?
200°C = 392°F. Formula: (200 × 1.8) + 32 = 360 + 32 = 392°F. This is a moderately hot oven. For reference: 180°C = 356°F (moderate), 220°C = 428°F (hot). Use the Celsius to Fahrenheit converter above for any oven temperature.
At what temperature are Fahrenheit and Celsius the same?
Fahrenheit and Celsius are equal at −40°. This is the only point where both scales read the same number: −40°F = −40°C. You can verify this using either formula: (−40 − 32) × 5/9 = −72 × 0.5556 = −40°C.
What is the difference between Fahrenheit and Celsius?
Fahrenheit and Celsius are two different temperature scales. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F. On the Celsius scale, water freezes at 0°C and boils at 100°C. The US, Cayman Islands, and a few other territories use Fahrenheit; the rest of the world uses Celsius. This temperature converter handles both directions.
