Convert body temperature from °F to °C
Input
98.6°F (normal body temperature)Output
37.0°C · 310.15 K98.6°F is normal human body temperature on the Fahrenheit scale. 37°C is the exact Celsius equivalent used in the rest of the world.
Convert temperature units instantly.
Convert between Celsius, Fahrenheit, and Kelvin easily
Base unit: Celsius
Available units: 3 temperature scales
Water freezes at 0°C and boils at 100°C at sea level. Widely used worldwide.
Water freezes at 32°F and boils at 212°F. Commonly used in the United States.
Absolute temperature scale where 0K is absolute zero. Used in scientific work.
Type your temperature number. Negative values are valid (e.g. −40 for the point where Celsius and Fahrenheit are equal).
Choose Celsius (°C) for most international contexts, Fahrenheit (°F) for US contexts, or Kelvin (K) for scientific work.
All three scale equivalents display instantly. The tool also shows whether the temperature is above or below water's freezing and boiling points for context.

Input
375°F (US recipe)Output
190.6°C · 463.7 KUS recipes use Fahrenheit oven temperatures. European and international recipes use Celsius. 375°F = 190°C is a common medium-high baking temperature.
Input
0 KOutput
−273.15°C · −459.67°FKelvin starts at absolute zero — the lowest theoretically possible temperature. 0 K is the absence of all thermal energy. Used in physics, chemistry, and engineering.
Common real-world scenarios where this tool saves time.
Home cooks and bakers
Recipes from the UK, Europe, and Australia use Celsius. US recipes use Fahrenheit. Converting oven temperatures accurately prevents over- or under-cooking.
Travellers and weather watchers
A 30°C day in Europe is 86°F — hot summer weather. A 20°F night in the US is −6.7°C — well below freezing. Temperature conversion prevents packing the wrong clothes.
Scientists and engineers
Physics and chemistry equations (gas laws, thermodynamics, blackbody radiation) require absolute temperature in Kelvin. Convert from Celsius or Fahrenheit readings to K for calculations.

Formula: °F = (°C × 9/5) + 32. Or equivalently: °F = (°C × 1.8) + 32. Examples: 0°C = 32°F (freezing), 100°C = 212°F (boiling), 37°C = 98.6°F (body temp), 20°C = 68°F (room temp).
Formula: °C = (°F − 32) × 5/9. Or equivalently: °C = (°F − 32) ÷ 1.8. Examples: 32°F = 0°C, 212°F = 100°C, 98.6°F = 37°C, 72°F = 22.2°C.
K = °C + 273.15. The Kelvin scale uses the same degree size as Celsius but starts at absolute zero (−273.15°C). 0°C = 273.15 K, 100°C = 373.15 K, room temperature (20°C) = 293.15 K.
−40° is the only point where Celsius and Fahrenheit have the same numerical value: −40°C = −40°F. This can be verified: (−40 × 1.8) + 32 = −72 + 32 = −40°F.
Standard room temperature is typically defined as 20–22°C (68–72°F) in residential settings, and exactly 20°C (68°F) or 25°C (77°F) in scientific contexts. ASHRAE recommends 18–24°C for occupied spaces.
