To convert a temperature from Celsius (°C) to Fahrenheit (°F) quickly, you can use the following shortcut formula:
°C x 1.8 + 32 = °F
Here's an example:
Convert 20°C to Fahrenheit.
20 x 1.8 + 32 = 68°F
Therefore, 20°C is equal to 68°F using this shortcut formula.
Note that while this shortcut formula is quick and easy to use, it may not provide as precise results as the full formula. If you need a more accurate conversion, you should use the full formula, which is:
(°C x 9/5) + 32 = °F
