What is a Pennyweight? Platinum weight, conversions and local use
Definition. The pennyweight (1.55517 g, one twentieth of a troy ounce) is the unit American jewellers and scrap buyers still quote in. One pennyweight equals 1.55517 grams, or 0.05000 troy ounces, which at today's platinum spot price works out to — GBP.
Where it is used. Repair work, casting weights and scrap gold offers in the US are almost always priced per pennyweight rather than per gram. The unit is the trading standard in United States jewellery trade.
Pricing conventions. A scrap buyer quoting per dwt is quoting on a unit roughly 1.5 times a gram, so always convert before comparing with an online per-gram offer. Platinum has almost no traditional-unit retail market: it is quoted per ounce or per gram, and this conversion is mainly used for jewellery weighing and industrial stock.
Good to know. The name survives from the medieval English penny, which literally weighed one pennyweight of silver.

Buying Platinum in United Kingdom: local market, taxes and premiums
At the live price shown above per pennyweight, the price you see here is the international XPT spot price converted into British Pound. Physical buyers in United Kingdom pay that reference plus a premium, and local trading is concentrated around London, the world's largest OTC bullion centre. Buyers there generally watch the twice-daily LBMA auction fixed in London as the day's reference.
Taxes and duties. Silver, platinum and palladium attract 20% VAT unless stored in an HMRC-approved bonded vault. Platinum is a much smaller market driven by autocatalyst and jewellery demand, so local availability is patchier and dealer spreads wider. That is why the shop price of platinum in GBP can sit noticeably above the spot value of the same pennyweight of metal.
How people usually buy. The common routes in United Kingdom are Royal Mint bullion, London dealers such as those around Hatton Garden, online dealers and LBMA-vaulted allocated accounts. The products most often quoted locally include Gold Britannia, Sovereign, 1 kg silver bars, allocated vault grams.
Local conventions. London is the pricing centre for the LBMA Gold Price, quoted per troy ounce and settled in loco London good-delivery bars. Before you buy, compare the dealer's asking price per pennyweight with the live platinum price above, and check the buy-back spread the same dealer offers — that round-trip cost matters more than a small difference in the headline GBP quote.
