Temperature Converter

A temperature widget needs two conversion helpers and one formatting helper. Keep the math separate from the display text so each function has one clear job.

Write these functions:

celsiusToFahrenheit(celsius) should convert Celsius to Fahrenheit and return the number.
fahrenheitToCelsius(fahrenheit) should convert Fahrenheit to Celsius and return the number.
formatTemperature(value, unit) should return display text such as "77 F" or "20 C".

Sample checks:

const fahrenheit = celsiusToFahrenheit(25);console.log(formatTemperature(fahrenheit, 'F'));const celsius = fahrenheitToCelsius(68);console.log(formatTemperature(celsius, 'C'));const freezingFahrenheit = celsiusToFahrenheit(0);console.log(formatTemperature(freezingFahrenheit, 'F'));const freezingCelsius = fahrenheitToCelsius(32);console.log(formatTemperature(freezingCelsius, 'C'));

Expected output:

txt

77 F20 C32 F0 C

The conversion functions should return numbers. formatTemperature should return the final string.

Solution

Solution:

function celsiusToFahrenheit(celsius) {  return (celsius * 9) / 5 + 32;}function fahrenheitToCelsius(fahrenheit) {  return ((fahrenheit - 32) * 5) / 9;}function formatTemperature(value, unit) {  return `${value} ${unit}`;}const fahrenheit = celsiusToFahrenheit(25);console.log(formatTemperature(fahrenheit, 'F'));const celsius = fahrenheitToCelsius(68);console.log(formatTemperature(celsius, 'C'));const freezingFahrenheit = celsiusToFahrenheit(0);console.log(formatTemperature(freezingFahrenheit, 'F'));const freezingCelsius = fahrenheitToCelsius(32);console.log(formatTemperature(freezingCelsius, 'C'));
