Result: 212.00Temperature is the one conversion a plain factor cannot do: each scale has a different degree size and a different zero point. So 0 °C is 32 °F, not 0 °F, and 100 °C is 212 °F. Celsius and Fahrenheit agree at exactly one temperature, -40°, which is the quickest way to check any conversion.

Questions
How do I convert Celsius to Fahrenheit?
Multiply the Celsius figure by 9/5 and add 32. For example 100 × 9/5 + 32 = 212 °F, the boiling point of water. To go the other way, subtract 32 first and then multiply by 5/9.
Is 0 °C the same as 0 °F?
No — 0 °C is 32 °F. Conversion between the two is affine: each scale has both a different degree size and a different zero point, so they never line up at zero. They agree at exactly one temperature, -40°, where -40 °C equals -40 °F.
What is absolute zero?
Absolute zero is the lowest temperature there is, the point of minimal particle motion. It is 0 K, which is -273.15 °C or -459.67 °F. Because the Kelvin scale starts there, a Kelvin figure can never be negative.
How do I convert Celsius to Kelvin?
Add 273.15 to the Celsius figure. A kelvin is exactly the same size as a Celsius degree, so only the zero point moves: 0 °C is 273.15 K and 100 °C is 373.15 K.
