Where does the exchange rate come from?

The rate box is pre-filled with the latest mid-market reference rate from our rate table, which is checked every hour against a public feed of daily reference rates. The line under the box shows when the rate was last updated and its source. Banks and card providers add a spread, so type your bank's rate over it when you need the exact amount.

How accurate is the conversion?

The math is exact to the precision your browser supports. The display rounds to 2 decimal places for USD and to 2 decimal places for THB, matching standard baht formatting conventions.

Can I convert THB back to USD?

Yes. Click the swap arrows button between the two fields to instantly reverse the conversion direction. The exchange rate adjusts automatically.

Is my data sent to any server?

No. All calculation happens locally in your browser using JavaScript. Nothing you type is transmitted anywhere.

What exchange rate should I use?

Use the mid-market rate for a reference figure, or your bank's buy/sell rate for actual transactions. The USD/THB rate fluctuates continuously, so always fetch a fresh rate before large transfers.

What is the Thai Baht symbol?

The Thai Baht uses the symbol ฿ and the ISO currency code THB. It is subdivided into 100 satang, though satang coins are rarely used in everyday transactions.
