Gaj and square feet are both units used to measure area. A gaj is commonly used in northern parts of India and is roughly equivalent to a square yard. Square feet is a more widely used unit internationally. To convert 150 Gaj to square feet, we can use the conversion rate that 1 Gaj equals 8.9 square feet (or 9 square feet in some regions). Therefore, to find the area in square feet, we simply multiply the Gaj (150 Gaj) by the conversion rate (8.9 Sq Ft/Gaj). So, 150 Gaj would equal 150 Gaj * 8.9 sq Ft/Gaj = 1335 square feet.
