To convert a temperature from Celsius (°C) to Fahrenheit (°F), use the following formula:
°F=(°C×95)+32°F=(°C\times \frac{9}{5})+32°F=(°C×59)+32
Or equivalently:
°F=(°C×1.8)+32°F=(°C\times 1.8)+32°F=(°C×1.8)+32
Steps to convert Celsius to Fahrenheit:
- Multiply the Celsius temperature by 9/5 (or 1.8).
- Add 32 to the result.
- The final number is 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
So, 20°C equals 68°F
. Quick estimation trick:
If you need a fast approximate conversion without a calculator, multiply the
Celsius temperature by 2 and then add 30. This gives a close estimate for most
everyday temperatures. For example, 15°C roughly converts to:
(15×2)+30=60°F(15\times 2)+30=60°F(15×2)+30=60°F
The exact value is 59°F, so this method is quite close
. Summary:
Method| Formula/Rule| Accuracy
---|---|---
Exact conversion| °F=°C×1.8+32°F=°C\times 1.8+32°F=°C×1.8+32| Precise
Quick estimation| °F≈°C×2+30°F\approx °C\times 2+30°F≈°C×2+30| Approximate
(±1-2°F)
This formula and trick will help you convert Celsius temperatures into Fahrenheit easily and accurately.
