Understanding Temperature Scales
Celsius (°C) is used by most of the world and is based on water: 0°C is the freezing point and 100°C is the boiling point at sea level.
Fahrenheit (°F) is primarily used in the United States. Water freezes at 32°F and boils at 212°F — a span of 180 degrees vs 100 in Celsius.
Kelvin (K) is the scientific temperature scale starting at absolute zero (-273.15°C). It uses the same increment size as Celsius but no degree symbol. 0 K = -273.15°C = -459.67°F.
Fun fact: The only temperature where Celsius and Fahrenheit are equal is -40° — that's right, -40°C = -40°F exactly!
Frequently Asked Questions
What is 100 degrees Fahrenheit in Celsius?
100°F equals 37.78°C. This is slightly above normal human body temperature (37°C or 98.6°F). Use the formula: °C = (°F − 32) × 5/9, so (100 − 32) × 5/9 = 37.78°C.
What is normal body temperature in Celsius and Fahrenheit?
Normal human body temperature is approximately 37°C or 98.6°F. This can vary slightly between individuals, typically ranging from 36.1°C to 37.2°C (97°F to 99°F).
What temperature is considered a fever?
A fever is generally considered to be 38°C (100.4°F) or higher. A low-grade fever is between 37.5°C and 38°C (99.5°F to 100.4°F). Temperatures above 39.4°C (103°F) are considered high fevers.
How do you convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8), then add 32. The formula is: °F = (°C × 9/5) + 32. For example, 25°C × 1.8 + 32 = 77°F.
What temperature is the same in Celsius and Fahrenheit?
The only temperature that is the same in both scales is -40 degrees. At this point, -40°C = -40°F exactly. This is where the two temperature scales intersect.
What is 0 degrees Celsius in Fahrenheit?
0°C equals 32°F. This is the freezing point of water at standard atmospheric pressure. The conversion is: (0 × 9/5) + 32 = 32°F.
What is room temperature in Celsius?
Room temperature is typically defined as 20°C to 22°C (68°F to 72°F). This range is considered comfortable for most people indoors. Scientific contexts often use 25°C (77°F) as a standard reference.
What is 350°F in Celsius for baking?
350°F equals approximately 177°C. This is a common moderate oven temperature used for baking cakes, cookies, and many other recipes. Most ovens round this to 175°C or 180°C.
Why does the US use Fahrenheit?
The United States uses Fahrenheit because it was the standard when the country was founded. Daniel Fahrenheit developed his scale in 1724. While most countries switched to Celsius (developed in 1742) after metrication, the US retained Fahrenheit for everyday use.
What is 20 degrees Celsius in Fahrenheit?
20°C equals 68°F. This is a comfortable room temperature. The calculation is: (20 × 9/5) + 32 = 36 + 32 = 68°F.
