Ampere to Ampere-Hour Calculator
This calculator helps you convert between Amperes (A), a measure of electric current, and Ampere-hours (Ah), a measure of electric charge, which is commonly used for battery capacity. Understanding this conversion is crucial for calculating how long a battery can supply a certain current, or what current a battery of a certain capacity can supply for a given time.
Current (Amperes):
Time (Hours):
Calculate Ampere-Hours
function calculateAmpereHour() {
var currentAmperesInput = document.getElementById("currentAmperes");
var timeHoursInput = document.getElementById("timeHours");
var ampereHourResultElement = document.getElementById("ampereHourResult");
var currentAmperes = parseFloat(currentAmperesInput.value);
var timeHours = parseFloat(timeHoursInput.value);
if (isNaN(currentAmperes) || isNaN(timeHours) || currentAmperes < 0 || timeHours < 0) {
ampereHourResultElement.textContent = "Please enter valid positive numbers for Amperes and Hours.";
return;
}
var ampereHours = currentAmperes * timeHours;
ampereHourResultElement.textContent = ampereHours.toFixed(2) + " Ah";
