Gold Converters: How to Use a Gold Calculator (Gram, Tola, 22K, 24K) — Complete Guide

Anyone who has bought, sold or inherited gold has run into the same problem: the numbers never line up cleanly. The jeweller quotes you a price per tola, the international market trades in troy ounces, your scale shows grams, and the receipt mentions 22K or 24K with a making charge on top. A good gold converter does all that maths for you instantly — but knowing the formulas behind it lets you check the numbers yourself and never get short-changed. This guide walks through every formula our calculators use, with worked examples you can follow on paper or with the live tools at Goldify.

The 8 converters on Goldify — what each one does

The master cheat sheet — every gold conversion constant

Tola ↔ Gram converter formula

Worked example: a 24-gram chain converts to 24 ÷ 11.664 = 2.058 tola. Going the other way, 5 tola of gold equals 5 × 11.664 = 58.32 grams. The Goldify TMR ↔ Grams converter does this instantly and also breaks the result into masha and ratti.

Tola ↔ Masha ↔ Ratti formulas

• 1 masha = 0.972 g
• 1 ratti = 0.1215 g
• 8 ratti = 1 masha
• 12 masha = 1 tola
• 96 ratti = 1 tola

Global unit converters — troy ounce, kilogram, tael, pennyweight, grain

International gold trades in troy ounces, not regular ounces. A troy ounce is heavier than a standard avoirdupois ounce, and getting the two confused is one of the most common buyer mistakes. The Goldify Global Unit Converters cover every major international standard.

Karat purity calculator — the 24-part rule

How to convert 18K to 24K (PAA)

When jewellers say 'convert 18K to 24K', they usually mean: how much pure 24K gold does my 18K piece actually contain? You cannot turn 18K into 24K by waving a wand — but you can calculate the pure-gold weight inside it.

Worked example: a 100 g 18K bracelet contains (18 ÷ 24) × 100 = 75 g of pure 24K gold. The remaining 25 g is alloy (copper, silver, etc.). The Goldify Karat Purity Checker does this for you in any unit — grams, tola, masha or ratti.

Money ↔ Gold converter formula

How much is 1 g of gold worth? (PAA)

Worked example: if today's 24K rate is PKR 320,000 per tola, then 1 g of 24K = 320,000 ÷ 11.664 = PKR 27,434. For 22K it is 27,434 × 0.9167 = PKR 25,148 per gram. The Goldify Money ↔ Gold converter handles this in any currency for any karat.

Polish calculator — accounting for melt loss

When old jewellery is melted down, a small amount is lost to oxidation, residue and refining waste. Jewellers call this 'polish' or 'cut'. Knowing how to calculate it stops you from being charged twice.

Impurity calculator — finding the alloy weight

Worked example: a 50 g 22K chain contains (22 ÷ 24) × 50 = 45.83 g of pure gold. Impurity = 50 − 45.83 = 4.17 g of alloy. Goldify's Impurity Calculator gives this instantly in tola/masha/ratti as well.

Gold Analyzer — combining everything in one view

The Gold Analyzer ties all the formulas together. Enter total weight, karat and current rate; it returns pure-gold weight, alloy weight, total monetary value, value in different currencies, and per-unit breakdown across grams, tola, masha and ratti. It is the single most useful tool when you walk into a jeweller's shop and want to verify everything in seconds.

How can I convert my gold to cash? (PAA)

Converting gold to cash is a four-step calculation. The Goldify Money ↔ Gold and Gold Analyzer tools do this for you, but it is worth understanding the logic so you can never be cheated at the counter.

1. 1.Weigh the piece on a calibrated scale and record the total weight in grams.
2. 2.Confirm the karat (22K, 21K, 18K…) — check the hallmark stamp.
3. 3.Apply the purity factor: pure gold weight = (karat ÷ 24) × total weight.
4. 4.Multiply pure-gold weight by the current 24K rate per gram, then subtract dealer margin and polish loss.

Are cash converters good for gold? (PAA)

Pawnbrokers and cash-for-gold shops are convenient, but they typically buy below the market rate to cover their own margin and risk. Reputable jewellers and assay offices usually offer better prices on the same gold. The single most important habit before selling is to know your gold's accurate weight, karat and current market value — exactly what a good gold converter gives you. Walk in informed and you will never accept a lowball offer.

How Goldify keeps its converters accurate

A gold calculator is only as good as the discipline behind it. Tiny errors compound — and on a 5-tola purchase, a rounding mistake can quietly cost you thousands. Here is how Goldify's converters are engineered to stay accurate across millions of calculations.

• Single source of truth — every unit price is computed from one 24K reference rate (rate per tola). Grams, masha and ratti prices derive directly from it, so no two views ever disagree.
• Exact constants — 1 tola = 11.664 g, 1 troy ounce = 31.1035 g, and karat purity = (karat ÷ 24). Hard-coded, never approximated.
• Multi-currency — every converter supports 100+ currencies via the same currency map used across the site.
• Mobile-first — every calculator is fully usable on a phone in a jewellery shop with one hand.
• No login required — calculators are public so any buyer can verify a price at the counter.
• Live rate sync — when the global rate updates, every converter refreshes instantly.
• Multilingual labels — Urdu, Hindi, Arabic, Bengali, Farsi, Chinese, Turkish and more.

Common conversion mistakes to avoid

1. 1.Confusing troy ounce (31.1035 g) with avoirdupois ounce (28.3495 g) — never use the wrong one for gold.
2. 2.Dividing first and multiplying later — that creates floating-point drift between unit prices.
3. 3.Using 11.66 instead of 11.664 for tola — small now, large over big quantities.
4. 4.Forgetting to apply the karat factor before multiplying by the 24K rate.
5. 5.Mixing up 'making charge' (a craftsman fee) with 'polish loss' (a melt loss). They are different and should be itemised separately.
6. 6.Trusting an unsigned receipt — always demand weight, karat, rate, polish, making and tax shown line-by-line.

Quick reference — the formulas you'll use most

Trust, but always verify with a calculator. The cheapest insurance against a bad gold deal is the formula in your pocket.

The bottom line

Gold maths is not as scary as it looks. Three constants and one purity formula handle nearly every real-world situation — from buying a wedding set in 22K to selling old jewellery for cash to converting between troy ounces and tola. Bookmark the Goldify converters, learn the formulas above, and you will never walk into a jewellery shop unprepared again.
