The density of rice husk can vary, but it typically ranges from 80-120 kg/m3.
The lignin content in rice husk can vary depending on the variety of rice and growing conditions, but it typically ranges from 18% to 24% on a dry weight basis.

The density of rice husk ash typically ranges from 1.8 to 2.2 grams per cubic centimeter.
The maximum gross calorific value of rice husk is approximately 14.8-16.2 MJ/kg, depending on the moisture content and specific composition of the husk. This value represents the energy content that can be obtained by burning rice husk in a controlled combustion process.
Over 660 million tons of the rice husk is consumed in the world for construction.
Brown rice was not invented. Brown rice is a product of milling rice without polishing off the natural rice bran layer. Only the husk is removed. Rice bran is normally brown in color. Some varieties of rice have black, violet or red bran layers therefore are called as such. Ancient people ate brown rice because the polisher wasn't invented yet and rice was kept in the husk and processed only before eating . Today millions of tons of rice are processed into white rice. Why? Brown rice spoils in 6 months because of the oil in the bran. If you don't keep them in the husk they oxidize.
chapatis have little more fat when compared to brown husk rice..if compared with white rice then certainly chapatis have less fat

To make the flour, the husk of rice or paddy is removed and raw rice is obtained. The raw rice is then ground to form rice powder, also known as rice flour.
Regular milled white rice, often referred to as "white" or polished" rice is the most common form of rice. The outer husk is removed, and the layers of bran are milled until the grain is white. Source: riceland.com
