Convert US Dollars to Thai Baht when you are building a Thailand travel budget, or reading a Baht price in Dollars. Neither side is the Euro, so USD/THB is a cross rate derived from the ECB’s Euro reference rates.
The US Dollar is still the currency most international invoices are written in. The Thai Baht is the practical currency for a Thailand budget. The table multiplies 1, 5, 10, 50, 100, 500, and 1,000 US Dollars by that same rate. Banks, bureaux, and card networks usually take a spread on top, so treat the result as a baseline rather than the quote you will be offered.
Questions about USD to THB
What is the USD to THB exchange rate today?
The rate on this page is the latest indicative ECB reference rate for converting US Dollars to Thai Baht, as returned by the Frankfurter API. The date beside it is the rate date. Over weekends and ECB holidays that date stays on the previous business day.
How many Thai Baht is 1 US Dollar?
Use the line “1 USD = … THB”. That unit rate is what the converter multiplies by. One hundred US Dollars is one hundred times the unit rate, before the result is rounded for display.
Will a bank give me this USD to THB rate?
Usually the retail rate is a little worse. This page shows a mid-market reference rate, not a bid or an offer. Building a Thailand travel budget, or reading a Baht price in Dollars is a sound reason to know the baseline, then compare the spread on the quote you actually have.
How often does the USD to THB rate change?
USD/THB is a cross rate derived from the ECB’s Euro reference rates. It changes when those Euro rates change, typically on ECB business days. The date on this page is the rate date, not necessarily today’s calendar date.
