Gaj to Katha calculator

What is gaj?

The Gaj, also spelled as Guz, is a traditional unit of length and area measurement predominantly used in parts of the Indian subcontinent, including India, Pakistan, and Bangladesh. Historically, its length varied regionally, ranging from 24 to 41 inches (approximately 610 to 1,040 millimeters). In contemporary usage, especially in northern India, the Gaj is standardized to equal one yard or 36 inches (0.9144 meters). When measuring area, one Gaj is equivalent to 9 square feet (0.8361 square meters). This unit remains prevalent in real estate and land transactions, particularly in rural and semi-urban areas, serving as a bridge between traditional practices and modern measurement systems.

What is katha?

The Katha is a traditional unit of land measurement predominantly used in parts of India, Nepal, and Bangladesh. Its value varies significantly across regions, reflecting local customary practices. For instance, in West Bengal and Bangladesh, one Katha is standardized to 720 square feet (approximately 66.89 square meters). In contrast, in Bihar, the size of a Katha can range from 750 to 2,000 square feet, with specific areas like Patna defining it as 1,361 square feet. In Assam, a Katha is commonly 2,880 square feet. This lack of standardization means that the exact area a Katha represents depends on the specific locality. Despite the official adoption of the metric system in these countries, the Katha remains in use, especially in rural and semi-urban areas, underscoring the enduring influence of traditional land measurement systems in South Asia.
