The full unit ladder
Ether has three units in everyday use. 1 ether = 10^9 gwei = 10^18 wei. That means 1 gwei = 10^9 wei. Wei is the indivisible base unit, gwei is the standard unit for gas prices, and ether is the display unit for balances and transfers.
Where you hit this in real work
RPC responses are in wei, gas prices are quoted in gwei, and users think in ether. A single converter that shows all three side by side lets you cross-check a balance, a fee cap, and a raw hex value without doing three separate divisions in your head.
