Convert Indonesian Rupiah to Thai Baht when you are turning Indonesian Rupiah into Thai Baht. Neither side is the Euro, so IDR/THB is a cross rate derived from the ECB’s Euro reference rates.
The Indonesian Rupiah is quoted in very large units, so a modest foreign amount becomes a long number. The Thai Baht is the practical currency for a Thailand budget. The table multiplies 10,000, 50,000, 100,000, 500,000, 1,000,000, 5,000,000, and 10,000,000 Indonesian Rupiah 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 IDR to THB
What is the IDR to THB exchange rate today?
The rate on this page is the latest indicative ECB reference rate for converting Indonesian Rupiah 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 Indonesian Rupiah?
Use the line “1 IDR = … THB”. That unit rate is what the converter multiplies by. One hundred Indonesian Rupiah is one hundred times the unit rate, before the result is rounded for display.
Will a bank give me this IDR 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. Turning Indonesian Rupiah into Thai Baht is a sound reason to know the baseline, then compare the spread on the quote you actually have.
How often does the IDR to THB rate change?
IDR/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.
