To convert 20 degrees Celsius to Fahrenheit, we can use the formula:
F = (C × 9/5) + 32
Substituting 20 for C in the formula gives us:
F = (20 × 9/5) + 32
First, we calculate 20 × 9/5, which equals 36.
Then, we add 32 to 36, resulting in 68.
Therefore, 20 degrees Celsius is equivalent to 68 degrees Fahrenheit.
