How many Romanian lei is 100 US dollars?

It is 100 multiplied by the lei-per-euro rate and divided by the dollars-per-euro rate, from the set dated beside the answer. In the dated set that ships with this page, the ECB publication of 2026-09-07, one euro was 5.2519 RON and 1.1622 USD, which gives 1 USD = 4.51893 RON, so 100 USD came to 451.89 RON and 1,000 USD came to 4,518.93 RON. The table under the converter lists round amounts from 1 to 100,000 dollars at whichever set the page loaded, and lists nothing when the set is more than seven days old.

Is this today's USD to RON exchange rate?

It is the most recent ECB reference set this site has fetched. The ECB publishes one set of euro reference rates on each working day, in the afternoon, Central European Time, and the server that answers this page asks for that file at most once every twelve hours. Before the day's publication, at a weekend or on a public holiday, the page shows the previous working day's set. It can also show the previous set for up to about a day after a new publication, because this site's copy is refreshed at most every twelve hours and a shared cache may hold the answer for twelve more. The date beside the answer is always the set you are looking at. It is not a market quote that moves during the day.

Does the National Bank of Romania publish a different rate?

The National Bank of Romania publishes its own daily reference rates for the leu, and they can differ slightly from the ECB reference rates. This page uses only the ECB set and prints that set's date, so you always know which publication a figure came from.

Why does the page say leu in one place and lei in another?

Leu is the singular and lei the plural: one leu, five lei. RON is the code for both, and it is the code the ECB file carries.

Is this what my bank will charge me for lei?

No. A reference rate is an observation published once each working day for statistical use, with no transfer fee, no exchange spread and no card scheme markup in it. A bank, a card issuer or a transfer service prices those in and settles at its own number.

Can I convert lei back to dollars?

Yes. The second table under the converter lists lei to dollars for round amounts, and the Swap button in the row under the panel, beside Copy, reverses the pair without a reload. In the 2026-09-07 sample that direction read 1 RON = 0.221291 USD. The RON to USD converter is the same tool opened on that direction.

The rates in the panel are the euro reference rates the European Central Bank published on the date shown. The server that answered this page keeps its own copy of that file, asked for at most once every twelve hours and handed unchanged to everyone that server answers, and the amount you type is converted in your own browser: it is never sent anywhere. The date beside the answer is the one you are actually looking at. The ECB publishes on working days only, so a Saturday or a public holiday shows the previous working day's set rather than a new one.
