Hello Friends Today, through this tutorial, I will tell you How to Joules to Volts calculator created using JavaScript with HTML? Below is an example of a Joules to Volts calculator created using JavaScript with HTML. This calculator allows users to input energy in joules and voltage in volts to calculate the resulting value of electrical charge in coulombs.

// Get the energy input value (joules)
const joules = parseFloat(document.getElementById('joules').value);
// Get the voltage input value (volts)
const volts = parseFloat(document.getElementById('volts').value);
// Calculate charge (coulombs)

This HTML file includes two input fields for entering energy in joules and voltage in volts, respectively. There’s also a button to trigger the calculation and a result paragraph to display the calculated charge in coulombs. When the button is clicked, the `calculateCharge` function is called, which performs the calculation and updates the result on the page.
