How the 500 grams of 900 silver price in JPY is calculated
Every figure on this page starts from the global silver spot price, which is quoted in US dollars per troy ounce. Right now that is $53.42 per ounce. A troy ounce weighs 31.1035 grams, so one gram of pure silver costs $1.72. We convert that to Japanese Yen at the live rate of 1 USD = 157.9208 JPY, giving ¥271.22 per gram of pure metal.
Because 900 silver is 90.0% pure, we multiply by 0.9, which gives ¥244.10 per gram and ¥7,592 per troy ounce. Multiplying by the weight of 500 grams gives the headline value of ¥122,051. Compared with yesterday's reference price, the value is up 3.15% in JPY terms.
The formula
Value = spot price per ounce ÷ 31.1035 × grams × purity × USD/JPY rate. Our calculator above applies this formula instantly to any weight and purity.

What moves the silver price
Silver behaves like a hybrid: it follows gold during risk-off periods but also tracks industrial demand from solar panels, electronics and electric vehicles. Because the market is smaller, silver usually moves more sharply than gold in both directions.
More than half of silver demand is industrial. The rest is jewelry, silverware, coins and bars, with India one of the largest buyers of physical silver. In Japanese Yen terms, the exchange rate matters as much as the metal itself: if the JPY weakens against the US dollar, the local price rises even when the dollar price is flat.
Tips before you buy or sell
- Compare dealer quotes with the melt value shown here. A fair buy-back offer for bullion is usually within 2–5% of spot; for jewelry and scrap expect 70–95%.
- Retail silver premiums are higher than gold premiums in percentage terms because the metal is cheaper per gram and bulkier to store. Sterling (925) items are valued on their silver content only.
- Weigh items on a calibrated scale in grams. Kitchen scales are often off by more than 1 gram, which can change the value of 500 grams of 900 silver materially.
- Check prices at different times of the day. The market trades almost 24 hours on weekdays and the most liquid period is the London and New York overlap.
- Remember that VAT, import duty and making charges are not included in spot prices. See our methodology for details.
Spot price vs. retail price
The spot price is the wholesale price for large, good-delivery bars traded between banks and refiners. Retail products cost more because of minting, assaying, insurance, shipping and dealer margin. Small coins and bars can carry premiums of 3–10% for gold and 10–30% for silver, while jewelry adds design and labor costs. When you sell, you receive a price based on spot minus the buyer's spread, so the figures on this page are the best neutral reference for negotiating.
