5 °C = 41 °F (degree Celsius → degree Fahrenheit)
5 °C = 41 °F
5 degrees Celsius (°C) equals 41 degrees Fahrenheit (°F). Temperature conversions are affine — the answer follows the standard scale formula, not a single multiplier.
Degrees Fahrenheit = Degrees Celsius × 1.8How 5 degrees Celsius compares to its arithmetic neighbours, converted to degrees Fahrenheit.

Celsius to Fahrenheit is affine, not multiplicative: F = C × 9/5 + 32. Room temperature 20 °C is 68 °F; body temperature 37 °C is 98.6 °F; a 200 °C oven is 392 °F. The 32 offset trips up calculators that treat the conversion as a simple factor — that error gets bigger at higher temperatures (200 °C × 1.8 alone is 360 °F, 32 short of correct). The two scales coincide only at −40°, a useful sanity check.
HVAC and cooking equipment sold to a US market both need the same Celsius-input conversion: a 21 °C thermostat setback is 69.8 °F, a 24 °C cooling setpoint is 75.2 °F, and a sous-vide egg held at 63 °C is 145.4 °F. Because home thermostats step in whole-degree Fahrenheit increments, a Celsius-native setting has to round to the nearest degree — 21.5 °C becomes either 70 °F or 71 °F depending on the rounding rule, a half-degree gap that's invisible to the user but matters to the firmware.
Begin with your temperature in degrees Celsius.
°F = °C × 9/5 + 32
The result is the equivalent temperature in degrees Fahrenheit. For example, 100 °C = 212 °F.
Temperature conversion is affine, not a single multiplication. The exact formula is shown below — it follows directly from the definitions of the degree Celsius and degree Fahrenheit scales.
°F = °C × 9/5 + 32

Water freezes at 0 °C. Room temperature is around 20–22 °C. Healthy human body temperature is about 37 °C. In degrees Fahrenheit, that gives you: 1 °C = 33.8 °F, 10 °C = 50 °F, 100 °C = 212 °F.
The degree Celsius (°C) is the SI-derived unit of temperature on a scale where 0 °C is the freezing point of water at standard pressure and 100 °C is the boiling point. Defined in 1742 by Anders Celsius (originally with the scale inverted) and refined repeatedly since, it shares its size of degree with the Kelvin: a change of 1 °C is identical to a change of 1 K. It is the everyday temperature unit almost everywhere outside the United States.
The degree Fahrenheit (°F) is the customary temperature scale in the United States, defined since 1968 such that water freezes at exactly 32 °F and boils at exactly 212 °F at standard pressure — giving 180 Fahrenheit degrees over a range of 100 Celsius degrees. The scale was proposed in 1724 by Daniel Gabriel Fahrenheit, who calibrated zero against a brine ice bath. To convert °F to °C, subtract 32 then multiply by 5/9.
