Precious Metal Valuation Calculus

Official industrial algorithm used by jewelry associations in Nepal.

Total = (Grams ÷ 11.6638) × Rate/Tola + Crafting Charge

1 Tola = 11.6638 grams = 100 Lal = 16 Aana

1 Lal = 0.116638 g | 1 Gram = 8.5735 Lal

Hallmark: 24K (99.9%) | Tejabi: 22K (91.6%)

Professional Computational Guidance

Nepal Gold Weight Converter (Tola, Gram, Aana, Lal)

Navigating traditional jewelry measurements in Nepal can be confusing, especially when balancing historical local scales with modern metric weights. Whether you are auditing family heirlooms, calculating custom jewelry fabrication costs, or verifying weights against the Federation of Nepal Gold and Silver Dealers' Association (FENEGOSIDA) benchmarks, accuracy is paramount.

Our automated gold calculator Nepal simplifies the process. This dynamic system converts instantly between international Grams (g) and traditional domestic units: Tola, Aana, Ratti, and Lal.

📐 Understanding the Nepal Gold Measurement System (1 Tola = 100 Lal)

In the Nepali gold market, the Tola (तोला) is the foundational baseline unit of mass. However, for smaller pieces of jewelry like rings, nose pins (Phuli), and earrings, jewelers break weights down into Aana and Lal (लाल).

The structural mathematical relationship governing the official Nepal gold unit scale follows these exact ratios:

  • 1 Tola = 100 Lal
  • 1 Tola = 16 Aana
  • 1 Tola = 11.6638 Grams
  • 1 Aana = 6.25 Lal
  • 1 Lal = 0.116638 Grams (commonly rounded to 0.1166g)

If a jeweler tells you an asset weighs 12 Aanas, that equates exactly to 75 Lal, which represents precisely 0.75 Tola of pure gold.

🧮 Mathematical Conversion Constants & Formulas

How to Convert Lal to Gram

Because 1 Tola equals 100 Lal and weighs exactly 11.6638 grams, a single Lal is exceptionally light.

Weight in Grams = Total Lal × 0.116638

Example: If you want to find out how many grams are in 15 Lal: 15 × 0.116638 = 1.7495 grams.

How to Convert Gram to Lal

If you have a digital kitchen scale or a laboratory balance measuring an item in grams, translate it back to traditional units using this division formula:

Weight in Lal = Weight in Grams ÷ 0.116638
