Temperature Converter
Convert temperatures accurately between Celsius (°C), Fahrenheit (°F), and Kelvin (K).
To convert Celsius to Fahrenheit, use °F = (°C × 9/5) + 32. To convert Fahrenheit to Celsius, use °C = (°F - 32) × 5/9. For Kelvin, add 273.15 to Celsius (K = °C + 273.15). Water freezes at 0°C (32°F) and boils at 100°C (212°F).
Temperature conversions use affine scalar transformations rather than simple multiplicative factors due to differing zero points.
Result
33.8
1 Celsius = 33.8 Fahrenheit
