29 degrees C to Fahrenheit.​
Shtirlitz [24]

Answer:

29 degrees Celsius are 84.2 Fahrenheit.

Step-by-step explanation:

In order to convert Celsius to Fahrenheit you can use this formula: F = C * 1.8 + 32.

Here we have F = 29 * 1.8 + 32 which equals 84.2. Instead of 1.8 you can use the fraction \frac{9}{5} if you wish so.
