Convert Vori to Catty (China) (vori to Catty (China))

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.

What is Catty?

Catty (China), known as Jin (斤) in Chinese, is a traditional unit of mass that remains widely used throughout mainland China and other Chinese-speaking regions. Although China officially uses the metric system, the Catty continues to be the preferred unit in many food markets, grocery stores, agricultural transactions, and everyday commerce.

The modern Chinese Catty has been standardized to equal 500 grams, making it closely integrated with the metric system. Consumers commonly purchase fruits, vegetables, meat, seafood, tea, and other products by the Catty, while manufacturers, exporters, and scientific organizations typically use grams and kilograms. Because of this dual usage, conversions between Catty and metric units are frequently required in trade, logistics, and product labeling.

Historically, the Catty has been part of traditional Chinese measurement systems for centuries and is closely related to other customary units such as the Liang (Tael). Despite the widespread adoption of metric measurements, the Catty remains an important cultural and commercial unit across China.
