How It Works

  1. 1

    Weight to Grams

    weightGrams = weight × conversionFactor (troy oz = 31.1035 g, oz = 28.3495 g, tola = 11.6638 g)

  2. 2

    Pure Gold Content

    pureGoldGrams = weightGrams × (purityPercent / 100)

    Price Normalization

    pricePerGram = goldPrice / gramsPerUnit (1 for gram, 31.1035 for troy oz, 28.3495 for oz)

    Total Value

    totalValue = pureGoldGrams × pricePerGram

Good to Know

Troy ounces (31.1 g) are the international standard for gold trading — don’t confuse them with regular ounces (28.35 g).

Most dealers pay 70–90% of melt value for scrap gold. Use this as a negotiation baseline.

Gold prices are always quoted per troy ounce in international markets (London Fix).

Estimated Value

10 g of 14K (58.3%) gold at $75.00 per gram is worth $437.25.

What this does

Calculates the melt value of gold based on weight, karat purity, and current gold price. Supports grams, troy ounces, regular ounces, and tola (Indian standard), with purity presets from 10K to 24K plus custom percentage entry. Multi-currency support covers USD, INR, GBP, CAD, and EUR for global gold markets.

Who it is for

Gold buyers, jewelry sellers, pawnbrokers, investors, and anyone evaluating scrap gold, coins, or bullion who needs a quick value estimate based on current market prices. Useful for Indian gold markets (tola + INR), UK bullion dealers (troy oz + GBP), and North American investors (grams/troy oz + USD/CAD).

How it works

Enter the weight of your gold item, select the purity karat (or enter a custom percentage), type the current gold price in your preferred unit (per gram, per troy ounce, or per ounce), and the calculator instantly shows the pure gold content and total value in your chosen currency.

Limitations

Uses manually entered gold prices, not live market data. Does not account for dealer premiums, refining fees, assay costs, numismatic value, or craftsmanship premiums. Actual buy/sell prices may differ from calculated melt value.

Reference ranges

Standard Karat Purities
24K = 99.9% (investment bullion). 22K = 91.7% (Asian/Middle Eastern jewelry). 18K = 75% (Western fine jewelry). 14K = 58.3% (US standard jewelry). 10K = 41.7% (US minimum legal gold content).
Gold Weight Conventions
Troy ounces (31.1 g) are the international standard for gold trading. Grams are used in most Asian and European markets. Tola (11.66 g) is standard in India and South Asia. Regular ounces (28.35 g) should not be confused with troy ounces.
Regional Pricing Notes
Gold prices vary by market: London Fix (USD/troy oz) is the global benchmark. Indian markets quote per 10 grams (INR). UK markets quote per troy ounce (GBP). Canadian and European markets follow their local currency per troy ounce.

How to use it

  1. 1.Enter the weightType the weight of your gold item and select the unit: grams, troy ounces, regular ounces, or tola.
  2. 2.Select the purityChoose a standard karat (24K, 22K, 18K, 14K, 10K) or enter a custom purity percentage for non-standard alloys.
  3. 3.Set the gold priceEnter the current gold price per gram, per troy ounce, or per regular ounce in your preferred currency.
  4. 4.Review the resultSee the pure gold content in grams and troy ounces, the total estimated value, and a weight breakdown across all units.

Multiply the weight in grams by the purity percentage to get pure gold grams, then multiply by the current price per gram. For example, 10 grams of 14K gold (58.3% pure) at $60/gram = 10 × 0.583 × 60 = $349.80.

A troy ounce equals 31.1035 grams and is the standard unit for precious metals trading worldwide. A regular (avoirdupois) ounce equals 28.3495 grams. Gold prices are always quoted per troy ounce in international markets, so using the wrong ounce type will give an incorrect value.

Karat measures gold purity on a 24-part scale. 24K is 99.9% pure gold, 22K is 91.7%, 18K is 75%, 14K is 58.3%, and 10K is 41.7%. The remaining percentage consists of alloy metals like silver, copper, or zinc that add strength and color.

A tola is a traditional South Asian unit of mass equal to approximately 11.6638 grams. It is the standard unit for gold trading in India, Pakistan, Bangladesh, and Nepal. One tola equals roughly 0.375 troy ounces.

The spot price reflects pure gold traded on financial markets. Physical gold items lose value due to: lower karat purity (14K is only 58.3% gold), dealer buy-back spreads (typically 5–20% below spot), refining costs for scrap gold, and the fact that craftsmanship premiums are not recoverable when selling.

Weigh your gold items, identify the karat stamp (usually marked on the piece), enter the current gold price per gram or troy ounce, and the calculator shows the melt value. Most dealers pay 70–90% of melt value for scrap gold, so use this as a negotiation baseline.
