The following code will display the subtotal item weight for cart and order items everywhere:

// Display the cart item weight in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_item_data', 10, 2 );
function display_custom_item_data( $cart_item_data, $cart_item ) {
    if ( $cart_item['data']->get_weight() > 0 ){
        $cart_item_data[] = array(
            'name' => __( 'Weight subtotal', 'woocommerce' ),
            'value' =>  ( $cart_item['quantity'] * $cart_item['data']->get_weight() )  . ' ' . get_option('woocommerce_weight_unit')
        );
    }
    return $cart_item_data;
}

// Save and Display the order item weight (everywhere)
add_action( 'woocommerce_checkout_create_order_line_item', 'display_order_item_data', 20, 4 );
function display_order_item_data( $item, $cart_item_key, $values, $order ) {
    if ( $values['data']->get_weight() > 0 ){
        $item->update_meta_data( __( 'Weight subtotal', 'woocommerce' ), ( $values['quantity'] * $values['data']->get_weight() )  . ' ' . get_option('woocommerce_weight_unit') );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

If you want to display the product weight instead, in cart and order items you will use:

// Display the cart item weight in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_item_data', 10, 2 );
function display_custom_item_data( $cart_item_data, $cart_item ) {
    if ( $cart_item['data']->get_weight() > 0 ){
        $cart_item_data[] = array(
            'name' => __( 'Weight', 'woocommerce' ),
            'value' =>  $cart_item['data']->get_weight()  . ' ' . get_option('woocommerce_weight_unit')
        );
    }
    return $cart_item_data;
}

// Save and Display the order item weight (everywhere)
add_action( 'woocommerce_checkout_create_order_line_item', 'display_order_item_data', 20, 4 );
function display_order_item_data( $item, $cart_item_key, $values, $order ) {
    if ( $values['data']->get_weight() > 0 ){
        $item->update_meta_data( __( 'Weight', 'woocommerce' ), $values['data']->get_weight()  . ' ' . get_option('woocommerce_weight_unit') );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

go to directory wp-content\plugins\woocommerce\templates\cart and add code there

 <tr>
         <th>Total Weight</th>
        <td><?php echo WC()->cart->cart_contents_weight . ' ' . get_option('woocommerce_weight_unit'); ?></td>
        </tr>
