magento2 – Magento 2 : Get product price as per order currency

I have placed order in euro

& tried to get product price in phtml file of an email template

using below code

/** @var $_item MagentoSalesModelOrderItem */

$_item         = $block->getItem();
$_order        = $_item->getOrder();
$helper        = $this->helper('VendorSalesHelperData');
$productObj    = $helper->getProductBySku($_item->getSku());

echo $_order->formatPrice($productObj->getPrice()); // This changes only currency symbol not price exg. ( product price in dollar $11 ) it converts into €11 not €8.

Any thoughts how it can be converted ?
