Kimchi premium + KRW conversion
Korea Tools — The Problems That Only Domestic-Exchange Users Have
Korean exchange prices are always slightly out of line with overseas venues. That gap is the kimchi premium: positive means Korea is expensive, negative means Korea is cheap. What matters is not the headline spread but whether anything survives transfer fees and FX costs — and for most people the arithmetic ends right there.
The kimchi premium calculator compares Upbit and Bithumb against Binance in real time and shows both the current spread and what an arbitrage would actually leave you with. The KRW converter turns your BTC, USDT and altcoin balances into won and dollars at the live rate — useful for sizing a portfolio scattered across several overseas venues in one go.
The two tools have different rhythms. The kimchi premium measures an opportunity that exists right now; the KRW converter measures the size of what you already hold. You open the first when the spread widens and the second when you sit down to tally your positions. Anyone running both a Korean and an overseas exchange ends up checking both.

Frequently Asked Questions
Does a high kimchi premium always mean profit?
No. Buying overseas and moving the coins to Korea costs transfer fees, exposes you to price movement during the transfer, and incurs an FX spread. All three have to come out first, and the calculator subtracts them to show what is left.
What does a negative premium mean?
It means Korean prices are below overseas ones, usually when domestic selling pressure is heavy. It is known as a reverse premium.
