function convertToVolts() {
// Get the energy in electron-volts input value
const energyInEV = parseFloat(document.getElementById('electronVolts').value);
// Conversion factor: 1 eV = 1.602 x 10^-19 volts
const conversionFactor = 1.602e-19;
// Calculate energy in volts
const energyInVolts = energyInEV * conversionFactor;
// Display the result
document.getElementById('result').innerHTML = `Energy in Volts: ${energyInVolts} V`;

This HTML file creates a simple Electron-volts to Volts calculator tool. Users can input energy in electron-volts (eV), and upon clicking the “Convert to Volts” button, the entered energy is converted to volts (V) using the conversion factor of 1 electron-volt (eV) equals 1.602 x 10^-19 volts. The calculated energy in volts is then displayed below the button.
