Look at the function currentConvert() the price should be an float

replace $price=10; with $price=10.00;

 * Convert currency
 * @param float $amount
 * @param string $from
 * @param string $to
 * @return float
public function currencyConvert($amount, $from, $to = null)
        if (empty($this->_currencyCache[$from])) {
            $this->_currencyCache[$from] = Mage::getModel('directory/currency')->load($from);
        if (is_null($to)) {
            $to = Mage::app()->getStore()->getCurrentCurrencyCode();
        $converted = $this->_currencyCache[$from]->convert($amount, $to);
        return $converted;


Go to System>Configuration>Currency Setup and make sure the currencies you are using are selected in the Allowed Currencies setting.

Nb: Your error means that the convert method cannot find a rate !

  • yes it is allowed Commented Nov 17, 2017 at 3:43

Make sure which is your base currency and to which currency you want to convert

Try this

$from = 'USD';
$to = 'HKD';
$price = 10;
$newPrice = Mage::helper('directory')->currencyConvert($price, $from, $to);
echo $newPrice;

Make sure you have allowed the currency from System > Configuration > Currency Setup and you have defined the currency rate in System > Manage Currency > Rates.

  • From USD to HKD is work but HKD to USD not work Commented Nov 17, 2017 at 3:42
