FAQ

How much is 1 USD in CNY? How do you calculate exchange rates?

USD/CNY fluctuates in real-time with no fixed value. In recent years it has traded roughly between 6.0–7.3 (check daily bank quotes for exact rates). Formula: CNY amount = USD amount × exchange rate. For example at 7.20, 100 USD = 100×7.20 = 720 CNY. Reverse conversion: USD amount = CNY amount ÷ rate. Enter the latest rate in this tool for precise calculations.

Does this tool provide real-time rates? Where do rates come from?

This tool does NOT offer real-time rate updates—because we commit to pure local calculation with no external API calls. You need to manually input the current rate (check daily mid-rates from the Fed, your bank's app, XE.com, or Google Finance). The advantage: your financial data never gets uploaded, works offline, ideal for sensitive scenarios. Great for quick estimates, teaching practice, contract clause calculations—use bank counter/app rates for actual exchanges.

What's the difference between cash buy rate, spot buy rate, sell rate, and mid-rate?

Banks typically quote four rates: Mid-rate (the central bank benchmark, for reference); Spot buy rate (bank buys foreign currency in your account, higher rate); Cash buy rate (bank buys physical foreign cash from you, lowest rate due to storage/transport costs); Sell rate (bank sells you foreign currency, highest rate). Use sell rate for buying foreign currency, buy rate for selling foreign currency back—cash exchange is less favorable than spot (spread ~0.5%–2%).

How much is 10,000 JPY in CNY? Quick mental math?

At recent rates around 0.047–0.052 (1 JPY ≈ 0.05 CNY), 10,000 JPY ≈ 470–520 CNY. Quick mental trick: drop two zeros then divide by 2 (10,000→100÷2≈500 CNY for rough estimate). Enter the actual daily rate in the tool for precise conversion.

How do I convert foreign prices seen while cross-border online shopping to my home currency?

Common cross-border shopping scenarios: US sites priced in USD, European sites in EUR, Japanese sites in JPY, UK sites in GBP, Korean sites in KRW. Formula: home currency price = foreign price × daily rate, but watch for added costs: international shipping (~$7–30), possible import VAT (cross-border e-commerce tax ~9.1%–23%), credit card foreign transaction fee (~1.5%), actual final cost typically 15%–30% higher than price × rate.

How much foreign currency should I exchange for travel? Budget estimation?

Rule of thumb estimates: Southeast Asia (Thailand/Malaysia/Indonesia) ~$30–70/person/day local currency equivalent; Japan/Korea ~$70–140/day; Europe/US/Australia ~$110–280/day (more including accommodation). Exchange a small amount of cash before departure (~$140–420 equivalent) for transit and small shops, use credit cards for large purchases (Visa/Mastercard usually offer better rates than cash exchange). Remaining foreign currency can be converted back after return with passport and exchange receipt.

How do I convert FOB/CIF prices in international trade quotes to home currency?

Trade quotes typically use USD. Convert to home currency: home currency = USD quote × settlement rate (bank spot buy rate). Notes: if contract specifies deferred payment, consider exchange rate risk (may need hedging/forward contracts); if quote includes freight/insurance (CIF), deduct those costs before calculating actual revenue; tax rebates (typically 13%) are additional income—don't simply calculate profit based on received amount.

Why are actual bank exchange rates different from what I see online?

Four reasons: (1) Online rates are mostly mid-rates; banks use buy/sell rates with spreads (~0.2%–1%); (2) Different banks quote slightly different rates (shop around); (3) Airport, hotel, and tourist exchange points offer the worst rates (can be 5%–15% worse); (4) Weekend/holiday rates stay frozen while international markets fluctuate, updating when business days open. For large exchanges, monitor rate trends and exchange in batches to average costs.

How much is 1 EUR in CNY?

EUR/CNY has traded roughly between 7.2–8.1 in recent years (check daily quotes for current rate). Formula: CNY = EUR × rate. For example at 7.80, 100 EUR = 780 CNY. The Euro is legal tender in 20 EU countries (Germany, France, Italy, Spain, Netherlands, etc.) and is the world's second-largest reserve currency.

How do you convert HKD and CNY? What is the linked exchange rate system?

HKD operates under a linked exchange rate system with 1 USD ≈ 7.75–7.85 HKD (strong/weak side convertibility undertaking), so HKD/CNY roughly tracks USD fluctuations. 1 HKD ≈ 0.9–0.95 CNY, recently around 0.92. Conversion: CNY = HKD×0.92, HKD = CNY÷0.92. When shopping in Hong Kong, pay by card—UnionPay/Visa/Mastercard all settle automatically at the daily rate, usually better value than cash exchange.

How are cross-border remittance fees calculated? How do they relate to exchange rates?

Cross-border remittance costs typically include: exchange spread (bank sell rate vs mid-rate, ~0.2%–1%) + cable/telegraphic transfer fee (~$14–28 per transaction for domestic banks) + intermediary bank fee (~$14–42) + receiving bank entry fee (charged by some banks). Small remittances (<$700) can incur fees of 3%–8%, large remittances (>$14,000) around 0.3%–1%. Choose appropriate channels: small amounts via Wise/PayPal/Apple Pay cross-border, large amounts via bank wire transfer.

Will the amounts I enter be uploaded? Is my privacy protected?

Absolutely not uploaded. All conversion logic uses pure client-side JavaScript running locally in your browser. Amounts you enter and currencies you select never generate any network requests—servers cannot see your financial data. Input is cleared immediately when you close the page; no cookies or localStorage used. Ideal for trade quote calculations, financial planning, cross-border investment analysis and other data-sensitive scenarios.

Glossary

Exchange Rate
The conversion ratio between two currencies, using direct/indirect quotation. Rates fluctuate in real-time and represent FX market trading prices.
Mid-market Rate
The central bank benchmark rate, midpoint between buy and sell rates, used as reference—actual transactions do not execute at this price.
Bid/Ask (Buy/Sell Rate)
Banks buy your foreign currency at the bid rate (less favorable for you), sell you foreign currency at the ask rate (even less favorable); the difference is bank spread revenue.
Spot / Cash Foreign Exchange
Spot FX is digital foreign currency in accounts (international transfers); Cash FX is physical banknotes. Cash buy rates are lower than spot buy rates due to storage/transport costs.
ISO 4217 Currency Codes
International standard three-letter currency codes like USD/CNY/EUR/JPY/GBP; first two letters are country codes (US/CN), third letter is currency initial (Dollar/Yuan).
Linked Exchange Rate System
The monetary system used by HKD, pegging the Hong Kong Dollar to USD within 7.75–7.85, maintained by HKMA foreign exchange intervention.
Exchange Gain/Loss
Profit or loss from converting foreign currency assets/liabilities to domestic currency due to rate fluctuations—an important risk in trade/cross-border investment.
Foreign Transaction Fee
Fee charged by card issuers for overseas credit/debit card purchases, typically 1%–2%; some premium cards (Visa Signature/Mastercard World) waive this fee.
