Daniel Gabriel Fahrenheit’s 0° was the freezing point of a brine made of equal parts ice, water, and ammonium chloride — the coldest mixture he could reliably produce in his Amsterdam lab in 1724. He set 96° to be roughly human body temperature, though we now measure that closer to 98.6°F.

Frequently asked questions
What is 350°F in Celsius?
350°F is 177°C. This is the most common medium-bake oven temperature in US recipes — for a UK or European oven, set it to 180°C (a 3 °C difference is well inside the natural variation between ovens). To convert any Fahrenheit to Celsius, subtract 32 then multiply by 5/9.
What are the common oven temperatures in Fahrenheit and Celsius?
A working table for cooks: 250°F is 121°C (very low / proofing), 300°F is 150°C (warm), 325°F is 163°C (low bake), 350°F is 177°C (medium bake), 375°F is 191°C, 400°F is 204°C (hot), 425°F is 218°C, 450°F is 232°C (pizza-oven hot), 475°F is 246°C, and 500°F is 260°C (broil).
How do I convert Celsius to Fahrenheit?
Multiply by 9/5 (or 1.8) then add 32. So 0°C is 32°F (freezing point of water), 20°C is 68°F (room temperature), 37°C is 98.6°F (normal body temperature), and 100°C is 212°F (boiling point of water at sea level).
What is normal body temperature in Celsius?
37 °C, which is 98.6 °F. Body temperature varies through the day by about half a degree Celsius — slightly lower in the morning, slightly higher in the late afternoon. A reading of 38 °C (100.4 °F) or higher is generally considered a fever.
What is room temperature in Celsius and Fahrenheit?
Room temperature is typically defined as 20 to 22 °C (68 to 72 °F). Scientific recipes and laboratory conventions often use 20 °C exactly. "Room temperature" in a recipe usually means whatever the kitchen happens to be at — for butter that means soft enough to dent but not melted, around 20 °C.
Why does the formula have 32 in it?
The Fahrenheit and Celsius scales were defined independently by different people in the 18th century. Daniel Fahrenheit set 0 °F at the freezing point of a brine solution and 96 °F at human body temperature; Anders Celsius set 0 °C at the freezing point of pure water and 100 °C at the boiling point. The 32-degree offset is just the freezing point of water on the older Fahrenheit scale.
