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.

Calculation Steps
- 110 g × 1 g/unit = 10 g
- 210 g × 58.3% purity = 5.83 g pure gold
- 3$75.00 per gram ÷ 1 g/unit = $75.00 per gram
- 45.83 g × $75.00/g = $437.25

About this calculator
Method, formulas, and limits.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, and international investors.
How it works
Enter the weight and unit, choose the karat purity (or a custom percentage), and set the gold price with its unit and currency. The calculator converts weight to grams, computes the pure gold content, normalizes the price per gram, and multiplies to get the total melt value with a full step-by-step breakdown.
Limitations
Estimates melt value only — it does not include dealer premiums, fabrication costs, taxes, or buy-back discounts. Actual prices paid by dealers vary by market conditions and item condition.
Key calculations
- Weight to Grams
- weightGrams = weight × conversionFactor (troy oz = 31.1035 g, oz = 28.3495 g, tola = 11.6638 g)
- 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
Reference ranges
- Typical Purity
- 24K = 99.9%, 22K = 91.7%, 18K = 75.0%, 14K = 58.3%, 10K = 41.7% pure gold.
- Dealer Pay Rates
- Scrap gold dealers typically pay 70–90% of melt value depending on the item and market conditions.
- Price Quoting
- International gold prices are quoted per troy ounce (31.1035 g). Gram prices are derived by dividing by 31.1035.
How to use it
- 1.Enter the weightType the weight of your gold item and select the unit: grams, troy ounces, regular ounces, or tola.
- 2.Select the purityChoose a standard karat (24K, 22K, 18K, 14K, 10K) or enter a custom purity percentage for non-standard alloys.
- 3.Set the priceEnter the current gold price with its unit (per gram, per troy ounce, or per ounce) and select your currency.
- 4.Review the resultRead the total value, pure gold grams, value per gram, and the full calculation steps.
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 75.0%, 14K is 58.3%, and 10K is 41.7%. The karat number divided by 24 gives the pure gold fraction.
