Formula and worked example

Price conversion: USD value = amount × input USD price; converted amount = USD value ÷ output USD price. USD has price 1. Blockchain units shift a decimal string exactly: 1 BTC = 100,000,000 satoshi; 1 ETH = 1,000,000,000 gwei = 1,000,000,000,000,000,000 wei.

Hypothetical example: 2 tokens at $100 each convert to $200, or to 4 tokens priced at $50. Exactly 1,000,000,000,000,000,001 wei converts to 1.000000000000000001 ETH. Prices exclude spreads, fees and slippage.

These estimates use bounded decimal arithmetic. They are scenario calculations, not trading instructions or forecasts.
