°F = (°C × 9/5) + 32

Here's a simple way to remember the formula:

- Multiply the Celsius temperature by 9.

- Divide the result by 5.

- Add 32 to the result.

For example, to convert 25°C to Fahrenheit:

°F = (25 × 9/5) + 32

°F = (225/5) + 32

°F = 45 + 32

°F = 77°F

Therefore, 25°C is equal to 77°F.
