The South Korean Won (KRW) is the official currency of South Korea, identified by the ISO 4217 code "KRW" and numeric code 410. Its symbol is ₩, and amounts are typically formatted with 0 decimal places (e.g., ₩1,234,567).
In software development, currency codes are essential for e-commerce, financial applications, and internationalization. The JavaScript Intl.NumberFormat API supports formatting amounts in KRW with locale-aware separators and symbols. Payment processors like Stripe and PayPal require ISO 4217 currency codes when processing transactions.
When building multi-currency applications, store amounts in the smallest unit (e.g., cents for USD) to avoid floating-point precision errors. Use the decimal places value (0) to correctly convert between major and minor units. APIs like exchangeratesapi.io and Open Exchange Rates provide real-time conversion rates for KRW.
