Fahrenheit to Celsius Converter
Convert Fahrenheit to Celsius: This guide will explain how to convert Fahrenheit to Celsius, show the relationship between these units, and provide examples for better understanding. By the end, you’ll be able to easily convert Fahrenheit to Celsius.
Introduction to Fahrenheit
The Fahrenheit scale is a temperature measurement system widely used in the United States and a few other countries. In the Fahrenheit scale, water freezes at 32°F and boils at 212°F under standard atmospheric conditions. This scale is mainly used for weather forecasts, cooking, and general household temperature measurements in regions where the imperial system is followed.
Some key facts about Fahrenheit:
- Water freezes at 32°F.
- Water boils at 212°F.
- Primarily used in the United States for everyday temperature measurements.
Introduction to Celsius
The Celsius scale, also known as the centigrade scale, is used worldwide, especially in countries that follow the metric system. In the Celsius scale, water freezes at 0°C and boils at 100°C under standard atmospheric conditions. This makes the Celsius scale much easier to understand in terms of everyday temperatures, and it is widely used in science, industry, and weather reporting outside of the United States.
Some key facts about Celsius:
- Water freezes at 0°C.
- Water boils at 100°C.
- Widely used in most parts of the world and in scientific calculations.
How to Convert Fahrenheit to Celsius
To convert a temperature from Fahrenheit to Celsius, you can use a simple formula. The conversion involves subtracting 32 from the Fahrenheit value and then multiplying the result by 5/9. This accounts for the difference in the freezing and boiling points of water in both scales and the difference in the scale intervals.
The formula is:
Celsius (°C) = (Fahrenheit (°F) - 32) × 5/9
This formula will give you the equivalent temperature in Celsius. It’s easy to apply and works for any temperature you need to convert from Fahrenheit to Celsius.
Examples of Fahrenheit to Celsius Conversion
Let’s look at a couple of examples to see how you can convert Fahrenheit to Celsius step by step.
Example 1: Convert 68°F to Celsius
Suppose you want to convert 68°F to Celsius. Here’s how to do it:
Step-by-Step Solution
Step 1: Use the conversion formula:
Celsius = (68 - 32) × 5/9
Step 2: Subtract 32 from 68:
Celsius = 36 × 5/9
Step 3: Multiply 36 by 5/9:
Celsius ≈ 20°C
Answer: Therefore, 68°F is equal to approximately 20°C.
Example 2: Convert 100°F to Celsius
Let’s say you want to convert 100°F to Celsius.
Step-by-Step Solution
Step 1: Use the conversion formula:
Celsius = (100 - 32) × 5/9
Step 2: Subtract 32 from 100:
Celsius = 68 × 5/9
Step 3: Multiply 68 by 5/9:
Celsius ≈ 37.78°C
Answer: Therefore, 100°F is equal to approximately 37.78°C.
