Convert Vori to Thulam (vori to Thulam)

Mass is the measure of the amount of matter in an object and its resistance to acceleration (inertia). The SI base unit is the kilogram (kg), now defined by fixing the Planck constant at h = 6.62607015 × 10⁻³⁴ J·s. Mass differs from weight: weight is the gravitational force acting on a mass (measured in newtons), while mass remains constant regardless of location. Common mass units include gram (g), milligram (mg), tonne (t = 1,000 kg), pound (lb), and ounce (oz).

A vori (also spelled bhori or bori, and written as ভরি in Bengali) is a traditional unit of mass used exclusively for weighing precious metals in Bangladesh and eastern India. Equal to approximately 11.66 grams (0.411 ounce), the vori is the standard measure in Bangladeshi and Indian gold and silver markets. Bangladesh and parts of India, maintain inventory records, and discuss piece weights with customers in bhoris. The unit has been used for centuries in jewelry craftsmanship across various Indian regions and remains deeply integrated into gold trading, jewelry manufacturing, and retail sales, jewelry design specifications, and customer expectations. While South Asian countries have officially adopted the metric system, the vori continues to be widely used in the jewelry trade because of long-standing cultural traditions and established business practices.

Thulam (symbol: tulam) is a traditional unit of mass used historically in South Asia, particularly for weighing precious metals such as gold and silver. In the standardized traditional system used for precious metals, one thulam is equal to approximately 11.6638038 grams. The unit is closely related to the tola and remains familiar in jewellery and bullion markets.

One thulam equals 11.6638038 grams, 0.0116638038 kilograms, and approximately 0.411428571429 ounces. It is mainly encountered in traditional weight systems, gold trading, jewellery, and historical measurement references.
