Hello @sarithapoleela ,

Magento only provide two-weight unit type which is KG and LBS under store -> configuration -> general section -> locale options ->weight  unit

You can customize it

need to override the file 

\magento\vendor\magento\module-directory\Model\Config\Source\WeightUnit.php

Add following code in 

\app\code\Custom\Directory\etc\di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Directory\Model\Config\Source\WeightUnit" type="Custom\Directory\Model\Config\Source\WeightUnit" />
</config>

In your 

app\code\Custom\Directory\Model\Config\Source\WeightUnit.php

namespace Custom\Directory\Model\Config\Source;

class WeightUnit extends \Magento\Directory\Model\Config\Source\WeightUnit
{
    /**
     * {@inheritdoc}
     */
    public function toOptionArray()
    {
        return [['value' => 'lbs', 'label' => __('lbs')], ['value' => 'kgs', 'label' => __('kgs')], ['value' => 'gms', 'label' => __('grams')]];
    }
}

Note: Be careful with your shipping methods. DHL, UPS, FedEx they allow only KG & LBS.
