Convert carats to grams instantly: 1 carat = 0.2 g. Type a value to see the result with the formula, swap direction with one tap, or pick any other weight units from the dropdowns. Free tool with formula and table, no sign-up.
What does this tool do?
The carats to grams converter is a fast, no-sign-up converter for weight units from milligrams to tolas and maunds. Enter any number in the Carat field and the equivalent in grams appears immediately, together with the conversion formula for transparency. You can reverse the conversion with the swap control, choose any of the 12 weight units from the dropdowns, and copy the result in one tap. Everything runs in your browser, so it works on slow connections and never sends your numbers anywhere.
Keep it bookmarked or on your home screen — utilities prove their worth through repetition, and the one you can open in two taps is the one you will actually use when the need strikes.

Carats to Grams formula
grams = carats ÷ 5
Equivalently, multiply by 0.2.
Example: 5 ct = 1 g.
Reverse: 1 g = 5 ct (see Grams to Carats).
Timing and randomness use the browser’s high-resolution clocks and cryptographic random source — the best available in a web page, accurate far beyond what everyday uses need. Display rounding is the only approximation.

What are these units?
Carat (ct): Exactly 200 mg. Used to weigh gemstones and diamonds.
Gram (g): One thousandth of a kilogram. Used for food, gold and small items.
Use cases in Pakistan
In Pakistani markets, weight is quoted in a mix of traditional and metric units. Jewellers price gold per tola, karyana shops sell desi ghee and dry fruit by the kilogram or the traditional pao, and butchers weigh meat in kilograms. Parcels sent through TCS or Leopards are billed per kilogram, while imported supplements, gym diet charts and foreign recipes arrive in pounds and ounces. Converting between these units keeps both shopping and cooking accurate.
These are the tools people recommend to each other on WhatsApp — simple, free, no install — because they solve the small problems everyone hits: timing something, picking fairly, testing a device. Bookmark the ones you use; they age well.
Limitations
Metric and avoirdupois factors are exact by definition; the tola (11.6638 g) and maund (40 kg) use their standard Pakistani values. Displayed results are rounded for readability — for jewellery or laboratory work, weigh on a calibrated scale rather than converting. This tool does not adjust for purity (karat) when weighing gold.
Convenience tools are not certified instruments: fine for everyday purposes, but do not stake safety, money or legal outcomes on a browser utility. Know which category your use falls into.
Frequently asked questions
How many grams are in a carat?
There are 0.2 grams in one carat.
How do I convert carats to grams?
grams = carats ÷ 5. Equivalently, multiply by 0.2. Example: 5 ct = 1 g.
How many grams are in one carat?
Exactly 0.2 g. Both units have exact international definitions, so this factor is not rounded — any rounding you see is only in how many decimals are displayed.
How do I convert grams back to carats?
Tap the swap button (⇄) above the result to reverse the direction instantly, or open the dedicated Gram to Carat converter page.
Can I convert between other weight units?
Yes. The From and To dropdowns list all 12 weight units this converter knows — pick any pair, for example Carat to milligram or kilogram to gram.
How accurate is the result?
It uses the exact defined values of both units and displays up to 10 significant figures — far more precision than any ruler, scale or bill needs. The conversion itself introduces no error; only the displayed decimals are rounded.
