Problem
We are required to write a JavaScript function that takes in a number in miles/gallon and return its equivalent km/litre.
Example
Following is the code −
const num = 25; const converter = (mpg) => { let LITRES_PER_GALLON = 4.54609188; let KILOMETERS_PER_MILE = 1.609344; const ratio = KILOMETERS_PER_MILE / LITRES_PER_GALLON; return Math.round(100 * mpg * ratio) / 100; }; console.log(converter(num));
Output
Following is the console output −
8.85
