Convert Celsius to Fahrenheit - JavaScript Solution & Walkthrough

01/16 Convert Celsius to Fahrenheit

The algorithm to convert from Celsius to Fahrenheit is the temperature in Celsius times 9/5, plus 32.

You are given a variable celsius representing a temperature in Celsius. Use the variable fahrenheit already defined and assign it the Fahrenheit temperature equivalent to the given Celsius temperature. Use the algorithm mentioned above to help convert the Celsius temperature to Fahrenheit.

function convertToF(celsius) {
  let fahrenheit;
  return fahrenheit;
}

convertToF(30);

Understanding the Challenge

The first challenge is this series seems to be a straightforward one. We are given a given a temperature in celsius. And what the challenge requires of us is to write a function convertToF() that converts the temperature from celsius to its equivalent in fahrenheit.

Fortunately, we have been given the formula.

We are told "The algorithm to convert from Celsius to Fahrenheit is the temperature in Celsius times 9/5, plus 32."

So, x celsius is equal to (x * (9/5)) + 32 fahrenheit.

Pseudocode

Given celsius,
  we multiply celsius by (9/5)
  we then add the result to 32
return the sum we get after adding 32.

Solving the Challenge

function convertToF(celsius) {
  let fahrenheit;
      fahrenheit = (celsius * (9/5)) + 32
  return fahrenheit;
}

convertToF(30); // 86

Congratulations!

You just cracked the first challenge in this series.

Cheers and happy coding!
