Why do cryptocurrencies have so many units?

Because base units (1 BTC, 1 ETH) are too large for everyday use. Smaller denominations let you quote gas fees, NFT prices, and micro-transactions without unwieldy decimals.

Where do the unit names come from?

Most are named after cryptography pioneers: Satoshi Nakamoto (BTC), Wei Dai (Wei), Hal Finney (Finney), Charles Babbage (milliether Lovelace — actually that's ADA). Solana uses 'lamports' after Leslie Lamport.

Can I convert between units here?

Why is the smallest unit so small (10⁻¹⁸)?

Ethereum's 10⁻¹⁸ wei matches the precision needed for fine-grained gas pricing — a single transaction's gas might cost 0.000000000000000001 ETH (1 wei). Smaller units = more flexibility in pricing.
