To convert temperatures between Celsius (°C) and Fahrenheit (°F), you can use the following formulas:

1. Celsius to Fahrenheit:
   $F = \left( \frac{9}{5} \times C \right) + 32$
2. Fahrenheit to Celsius:
   $C = \frac{5}{9} \times (F - 32)$

Let's perform the conversions:

1. Convert 31°C to Fahrenheit:

$F = \left( \frac{9}{5} \times 31 \right) + 32 = 55.8 + 32 = 87.8°F$

2. Convert 92°F to Celsius:

$C = \frac{5}{9} \times (92 - 32) = \frac{5}{9} \times 60 = 33.33°C$

So, the conversions are:

• 31°C = 87.8°F
• 92°F = 33.33°C
