How to convert CELSIUS to FAHRENHEIT

Celsius is the standard in most countries and in all scientific contexts: water freezes at 0 and boils at 100. Fahrenheit is used primarily in the United States, so you encounter it in American weather forecasts, cooking recipes, oven settings, and medical readings. Knowing what 350 degrees Fahrenheit means for your oven or what 98.6 F signals about a fever requires moving between the two scales.

The formula is: multiply the Celsius value by 9/5 (or 1.8) and add 32. BoltConverter applies that formula the moment you type, so you get the Fahrenheit equivalent without any manual arithmetic. Common landmarks: 0 C is 32 F (freezing), 20 C is 68 F (comfortable room temperature), and 37 C is 98.6 F (normal body temperature).
