## Implement a temperature converter

Implementing a temperature converter in Python will teach you a lot of things.

It is a beginner project you need to have done at least once and it will teach you a lot.

1. User Input and Output. You will learn how to accept user input and display output in the terminal using Python’s built-in input() and print() functions.
2. Variables and Data Types. You will learn how to use variables to store data and manipulate it using arithmetic operators. Additionally, you will learn about data types such as integers, floats, and strings.
3. Basic Math Operations. You will learn how to perform basic math operations such as addition, subtraction, multiplication, and division in Python.
4. Conversion Formulas. You will learn about the formula used to convert between Celsius and Fahrenheit temperature scales.
5. Float precision You will learn how to work with float precision and how it matters for the user experience.

## Project Description

Create a temperature converter in Python from Fahrenheit to Celsius using the formula

°𝐶=(°𝐹−32)×5/9

#### Project

• Prompt the user for temperature in Fahrenheit
• Calculate the temperature in Celsius
• Print the result

• 7523.89

## Step 1 Prompt the user

You can use the built-in function input() to prompt the user. Notice that it returns string, which needs to be converted to float for further calculations. That can be done with the built-in function float().

# 1: prompt the user
fahrenheit_str = input('Input Fahrenheit: ')
fahrenheit = float(fahrenheit_str)

## Step 2 Calculate the Celsius temperature

We will use the formula. Notice that you can use round() to get 2 digits (or any number of precision if you change the second argument).

°C=(°F−32)×5/9

# 2: Caculate the celsius temperature
celsius = (fahrenheit - 32)*5/9
celsius = round(celsius, 2)

## Step 3 Display the result

You can use the built-in function print() to display the result to the user.

# 3: dispaly result
print('Celsius', celsius)

## The full code

The full code is given here.

# 1: prompt the user
fahrenheit_str = input('Input Fahrenheit: ')
fahrenheit = float(fahrenheit_str)

# 2: Caculate the celsius temperature
celsius = (fahrenheit - 32)*5/9
celsius = round(celsius, 2)

# 3: dispaly result
print('Celsius', celsius)
