40 degrees Celsius is what in Fahrenheit?

To convert 40 degrees Celsius to Fahrenheit, you can use the formula:

F = (C × 9/5) + 32

Substituting 40 for C, the equation looks like this:

F = (40 × 9/5) + 32

Calculating this step by step:

1. Multiply 40 by 9: 40 × 9 = 360
2. Now divide by 5: 360 ÷ 5 = 72
3. Finally, add 32: 72 + 32 = 104

So, 40 degrees Celsius is equivalent to 104 degrees Fahrenheit.
