What does 'conserving pure-gold content' mean?

Every karat value represents a fraction of pure gold — 24K is 100% pure, 18K is 75%, and so on. Karat Converter finds the weight in the target karat that contains the exact same mass of pure gold as your original piece, so the comparison is apples-to-apples.

Which karats can I convert between?

The tool supports all standard karats: 24K, 22K, 21K, 18K, 14K, 10K, and 9K. You can convert in any direction — from higher to lower karat or vice versa.

How does it show me the value?

After calculating the equivalent weight it multiplies the pure-gold content by the current market price for your country and displays the result in your local currency, so you immediately know what the gold is worth regardless of karat.

Is this useful when buying or selling second-hand jewellery?

Absolutely. If a seller quotes a price for a 21K piece and you want to compare it against a 18K piece by weight, Karat Converter gives you the normalised pure-gold weight and value for a fair comparison in seconds.

What it does

Karat Converter answers a question jewellers and gold traders face constantly: if I have gold of one karat, how much would I need in a different karat to get the same amount of pure gold — and what is that weight worth? Enter a weight and starting karat, select the target karat, and the tool calculates the equivalent weight that contains the same pure-gold content, then shows you the shared value in your local currency at today's live rate. It is indispensable when re-working jewellery, comparing quotes, or trading between karats. Carbide runs the entire conversion on your device — free, offline-capable, no sign-up, and completely private.
