Which formula converts Celsius to Fahrenheit?

Which formula converts Celsius to Fahrenheit?

• A. F = (C * 1.8) + 32
• B. C = (F - 32) / 1.8
• C. F = C + 273.15
• D. F = (C * 1.8) - 32

Answer: (A)

Converting Celsius to Fahrenheit uses the linear relation F = (C × 1.8) + 32, where 1.8 is 9/5 and 32 offsets the freezing points between the two scales. This formula directly scales the Celsius temperature and then shifts it so that 0°C corresponds to 32°F. The other options either convert in the opposite direction (F to C), convert Celsius to Kelvin, or incorrectly subtracts 32 instead of adding it, giving the wrong Fahrenheit values.
