Convert Temperature Units Online with Fahrenheit (°F) to Celsius (°C) Conversion

Convert Fahrenheit to Celsius using the exact conversion factor. This page provides the formula, reference values, and practical context for engineering, technical calculations, and professional measurement use.

Conversion Formula

°C = (°F − 32) × 5/9

Temperature conversions use an offset formula, not a single multiplier. Apply the relationship shown above (for example Fahrenheit (°F) to Celsius (°C)) so absolute scale differences (such as the 273.15 K offset for Celsius) are handled correctly.

Example

Convert 1 F to C.

• Step 1: Write the formula: °C = (°F − 32) × 5/9
• Step 2: Substitute: F = 1
• Step 3: Result: -17.222222 C

So, 1 F = -17.222222 C.

About the Units
