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).

Thulam is a traditional unit of mass historically used in South Asia, particularly for weighing precious metals such as gold and silver. The unit is closely related to the well-known Tola measurement and remains familiar in jewelry trading, bullion markets, and traditional weight systems across countries including India, Sri Lanka, Bangladesh, Nepal, and Pakistan.

Before the widespread adoption of the metric system, Thulam was commonly used by jewelers, merchants, and traders to measure valuable commodities. Even today, some gold dealers and jewelry businesses continue to reference Thulam-based weights alongside modern metric units such as grams and kilograms. This makes conversions between Thulam and metric units important for valuation, certification, hallmarking, insurance, and international trade.

Thulam belongs to a broader family of traditional South Asian weight units that includes Tola, Vori (Bhori), and Aana. Because global precious metal markets use grams and kilograms as standard units, Thulam is often converted into metric measurements when comparing prices, preparing documentation, or conducting cross-border transactions.

Today, Thulam serves as a link between traditional precious-metal trading practices and modern measurement systems, helping preserve historical measurement traditions while supporting contemporary commerce and record-keeping.

Troy ounce (symbol: oz t or ozt) is a unit of mass used primarily for weighing precious metals such as gold, silver, platinum, and palladium. One troy ounce is exactly equal to 31.1034768 grams, making it heavier than the avoirdupois ounce, which is commonly used for everyday goods. The troy ounce is the international standard for pricing and trading bullion, coins, and precious metals, and it is frequently converted to grams, kilograms, and avoirdupois ounces in global commodity markets and jewelry applications.
