Answer 1

You need to create new field you wish to save the value(qty_in_kgs) in sales_order_item table first. Than by using the plugin, you can save the value in table as below

In Magento 2 without using fieldset you can also copy custom data from quote item to order item by using plugin.

create di.xml in your module etc folder.

app/code/Vender/Yourmodule/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">
    <type name="Magento\Quote\Model\Quote\Item\ToOrderItem">
        <plugin name="your_quote_to_order_item" type="Vender\Yourmodule\Model\Plugin\Quote\QuoteToOrderItem"/>
    </type>
</config>

Create a class to your module and define a function. app/code/Vender/Yourmodule/Model/Plugin/Quote

Create QuoteToOrderItem.php file

<?php
namespace Vender\Yourmodule\Model\Plugin\Quote;

use Closure;

class QuoteToOrderItem
{
    /**
     * @param \Magento\Quote\Model\Quote\Item\ToOrderItem $subject
     * @param callable $proceed
     * @param \Magento\Quote\Model\Quote\Item\AbstractItem $item
     * @param array $additional
     * @return \Magento\Sales\Model\Order\Item
     * @SuppressWarnings(PHPMD.UnusedFormalParameter)
     */
  public function aroundConvert(
        \Magento\Quote\Model\Quote\Item\ToOrderItem $subject,
        Closure $proceed,
        \Magento\Quote\Model\Quote\Item\AbstractItem $item,
        $additional = []
    ) {
        /** @var $orderItem \Magento\Sales\Model\Order\Item */
        $orderItem = $proceed($item, $additional);//result of function 'convert' in class 'Magento\Quote\Model\Quote\Item\ToOrderItem' 
        $orderItem->setQtyInKgs($item->getQtyInKgs());//set your custom value.
        return $orderItem;// return an object '$orderItem' which will replace result of function 'convert' in class 'Magento\Quote\Model\Quote\Item\ToOrderItem'
    }

}

I didn't give try to this but it should work. Once the value saved in order item table, you can show it wherever you want and proceed further.
