What is the correct formula to convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (which is 1.8) and then add 32. This works because the Fahrenheit and Celsius scales share the same freezing point for water (0°C equals 32°F) and a different but fixed slope between the scales (100°C difference corresponds to 180°F difference). So the correct formula is F = (C × 1.8) + 32, or F = (C × 9/5) + 32. Adding 273 shifts Celsius to Kelvin, not Fahrenheit. Dividing by 1.8 and subtracting 32 misapplies both the scale factor and the offset. Using a factor of 0.5 is also incorrect for this conversion. For a quick check, 0°C becomes 32°F, and 100°C becomes 212°F.
