Enter an ARB amount — the default is 1,000 ARB. ARB amounts are shown to 2 decimal places.
Or enter a USD amount to see how much ARB it buys at the current price.
Both fields update each other in real time — the converter is fully bidirectional.

Example: At a live ARB price of $0.50, entering 1,000 ARB gives $500.00 USD. Entering $1,000 gives 2,000.00 ARB. DAO treasury context: 3,000,000,000 ARB × $0.50 = $1.5 billion USD treasury value. For the what-if table: $1,000 invested at the March 2023 airdrop launch at $1.40 bought 714.29 ARB, worth $357.14 today at $0.50 — a loss of $642.86 or −64%. Invested at the June 2024 post-ATH low of $0.85, the same $1,000 bought 1,176.47 ARB, worth $588.24 today — a loss of $411.76 or −41%.
