Convert between degrees Celsius (°C), degrees Fahrenheit (°F), and kelvin (K). Unlike linear units, temperature scales have different zero points, so conversions require offset formulas, not simple multiplication. Kelvin (K) is the SI base unit; 0 K is absolute zero (−273.15 °C).
This temperature converter transforms values from Celsius (°C) to Fahrenheit (°F). Temperature scales have different zero points, so conversion uses an offset formula, not a simple multiplier.
Degrees Celsius (°C) is a metric temperature scale where 0 °C is the freezing point of water and 100 °C is its boiling point at standard pressure.
Degrees Fahrenheit (°F) is used primarily in the United States; 32 °F is the freezing point of water and 212 °F is its boiling point.
°F = (°C × 9/5) + 32
°F = (°C × 9/5) + 32
The conversion formula transforms °C to °F. Values are first converted to kelvin (K), the SI base unit, then to the target scale, which avoids rounding errors from chained offset formulas. A change of 1 °C equals a change of 1 K, but 0 °C ≠ 0 K.
50 °F = (10 °C × 9/5) + 32 = 50 °F
