Degrees Celsius to Degrees Fahrenheit
1 degree Celsius = 33.8 degrees Fahrenheit · 1 °F = -17.222 °C
1 degree Celsius = 33.8 degrees Fahrenheit
How it’s calculated
°F = °C × 9/5 + 32
- Temperature scales have different zero points, so the conversion adds or subtracts an offset as well as scaling.
- 1 °C = 33.8 °F · 1 °F = -17.22222222 °C

Use the exact scale definitions
Temperature scales have different zero points, so this is not a single multiplication: it adds or subtracts an offset as well as scaling. The definitions are exact (0 °C = 273.15 K; 1 °F = 5/9 K; absolute zero = −459.67 °F). Source: BIPM SI Brochure (9th ed.); NIST SP 811 / Handbook 44.
Step 1: scale
Scale by 9/5 (a Fahrenheit degree is 5/9 the size of a Celsius degree).
Step 2: add the offset
Add 32 to shift the zero point (water freezes at 32 °F).
Round the answer
Rounded to 5 significant figures.
Answer: 33.8 °F · Temperature readings include an offset; for a temperature difference use only the scale factor.
