What are Japanese and Hongkong Tael? Types of Tael Gold
The Tael (兩 / liǎng) is a traditional East-Asian unit of mass historically used for weighing precious metals such as gold and silver. Its exact weight varies by region — for example, Japan and Hong Kong use slightly different Tael standards. To ensure transparency, GoldPriceZ displays the precise mass in grams and troy ounces for each Tael-based price.
1. Japanese Tael
Japan’s traditional “Ryō” or Tael is defined in modern references as:
- 37.5 grams (g)
- = 1.2056 troy ounces (ozt)
This conversion aligns with international metrological sources such as the Ministry of Economy, Trade and Industry (METI) of Japan and the U.S. National Institute of Standards and Technology (NIST). It represents the standard 37.5-gram Tael used for most bullion and historical references.

2. Hong Kong Tael (CGSE Bullion Standard)
The Hong Kong Tael used in bullion trading is defined by the Chinese Gold & Silver Exchange Society (CGSE) as:
- 37.429 grams (g)
- = 1.20337 troy ounces (ozt)
This value serves as the official bullion-market Tael in Hong Kong and Macau. It differs slightly from Japan’s Tael but is the globally accepted standard for Hong Kong gold bar weights.

3. Other Regional Tael Variants
Some regional markets and weighing-equipment standards in East and Southeast Asia define a Tael as approximately 37.7993 g (1.21528 ozt). This heavier variant is primarily used in non-bullion or jewelry trade contexts. To maintain global comparability, GoldPriceZ displays the exact gram value alongside each unit label.
4. Transparency and Standardization
GoldPriceZ follows internationally recognized conversion methods for traditional mass units. Our conversions are based on the scientific definition of the troy ounce (31.1034768 g) as published by the U.S. National Institute of Standards and Technology (NIST) and verified against regional trade standards from the CGSE (Hong Kong) and METI (Japan).
It should be noted that there might be some variation in weight due to rounding or measurement conventions. Therefore, we provide the exact mass/weight used in our price calculations in the reference section of all gold and silver price-related pages. This ensures full transparency and consistency across our global listings.
Disclaimer: GoldPriceZ publishes traditional weight data for informational and educational purposes only. Variations in local definitions of the Tael (e.g., 37.429 g, 37.5 g, 37.7993 g) may exist depending on exchange or region. All conversions on this website follow verifiable standards from reputable institutions such as NIST, METI, and CGSE. Users should verify local bullion specifications before making commercial transactions.

Silver Purity/types:
Unlike gold, silver is typically not classified by karats. Instead, silver purity is usually expressed as a percentage or parts per thousand. The most common purities are:
- Fine Silver (99.9%): Used in investment-grade bullion, coins, and bars.
- Sterling Silver (92.5%): Common in jewelry, silverware, and decorative items.
- Coin Silver (90%): Previously used in coins, now less common.
- Other Alloys: Lower purity silver used in budget or industrial applications.
Silver purity is often marked with stamps like "999," "925," or "900" to indicate the purity level.
