Buffalo milk contains approximately 7-8% fat on average, with 7.2% being the standard cited figure. This is significantly higher than cow milk (typically 3.5-4%). The higher fat content makes buffalo milk richer and more suitable for products like ghee, butter, and milk powder. 4.5% is closer to cow milk, while 9-10% are too high.

Approximately 71% of Earth's surface is covered by water, while land constitutes about 29%. This ratio is a fundamental characteristic of our planet, with oceans, seas, and other water bodies dominating the surface area. The Pacific Ocean alone covers nearly one-third of Earth's surface. This distribution of land and water significantly influences global climate patterns, weather systems, and biodiversity. The 71:29 ratio is well-established in geography and Earth sciences.

India's road density is approximately 75 km per 100 sq. km, reflecting the extensive road network across the country. This figure represents the average length of roads per unit area nationwide.
