To convert Celsius (°C) to Fahrenheit (°F), use the precise formula:
°F=(°C×1.8)+32°F=(°C\times 1.8)+32°F=(°C×1.8)+32
This means you multiply the Celsius temperature by 1.8 (or 9/5) and then add 32 to get the temperature in Fahrenheit
Example:
Convert 20°C to Fahrenheit:
°F=(20×1.8)+32=36+32=68°F°F=(20\times 1.8)+32=36+32=68°F°F=(20×1.8)+32=36+32=68°F
Quick Estimation Trick
For a rough estimate without a calculator, you can multiply the Celsius temperature by 2 and then add 30:
°F≈(°C×2)+30°F\approx (°C\times 2)+30°F≈(°C×2)+30
This is fairly accurate for typical weather temperatures but may be off by a few degrees
Summary:
- Exact: °F=(°C×1.8)+32°F=(°C\times 1.8)+32°F=(°C×1.8)+32
- Quick estimate: °F≈(°C×2)+30°F\approx (°C\times 2)+30°F≈(°C×2)+30
Use the exact formula for precise conversions and the quick trick for mental math or approximate values.
