About Temperature Scales

The Fahrenheit and Celsius scales are two common temperature scales used around the world.

Celsius Scale

Water freezes at 0°C and boils at 100°C (at standard atmospheric pressure)
Used in most countries worldwide as part of the metric system
Also known as the centigrade scale

Fahrenheit Scale

Water freezes at 32°F and boils at 212°F (at standard atmospheric pressure)
Commonly used in the United States and its territories
Created by Daniel Gabriel Fahrenheit in 1724

Reference Points

Room temperature: approximately 20-22°C or 68-72°F
Normal human body temperature: approximately 37°C or 98.6°F
Absolute zero: -273.15°C or -459.67°F

Fahrenheit to Celsius: °C = (°F - 32) × 5/9

Celsius to Fahrenheit: °F = (°C × 9/5) + 32

Frequently Asked Questions (FAQ)

What is the formula to convert Fahrenheit to Celsius?

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit value and multiply the result by 5/9.
°C = (°F - 32) × 5/9

What is the formula to convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit, multiply the Celsius value by 9/5 and add 32.
°F = (°C × 9/5) + 32

Why are there two temperature scales?

Celsius is widely used in most countries and is part of the metric system, while Fahrenheit is common in the United States. This calculator bridges the gap between these two systems, functioning as an essential measurement converter.

Can I use this to convert other units like grams to milliliters or square feet to meters?

This specific tool is focused on temperature, but similar unit conversion tools exist for values such as convert grams to milliliters, square feet to meters, or convert degrees to milliradians. If you're looking for a broader measurement converter or conversion calculator, there are other tools designed for those conversions.

Is this a real-time calculator?

Yes. As soon as you input a value in either field, the corresponding value is automatically updated using the correct formula.
