How this service works
Convert between wei, kwei, mwei, gwei, microether, milliether and ether with exact BigInt arithmetic. Decimal strings of any magnitude convert without floating-point error. Use this when an agent needs to exact Ethereum unit conversion — no float errors.
Output
A converted numeric value expressed in the target Ethereum denomination, computed with exact BigInt arithmetic so large or fractional amounts carry no floating-point rounding error.
Example use cases
Gas fee estimation in ether
“I have a gas cost of 42000000000000 wei from a transaction receipt — convert that to ether so I can display it in a human-readable format.”
Smart contract value denomination
“I need to pass 2.5 ETH to a contract but it expects the amount in gwei — what is 2.5 eth in gwei exactly?”
DeFi slippage display conversion
“My DeFi app shows a swap fee of 500000 mwei — convert that to ether so I can show the user the actual cost in ETH.”
Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/crypto/wei-eth-converter?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need exact, lossless Ethereum unit conversion for any combination of wei, kwei, mwei, gwei, microether, milliether, and ether — especially when floating-point precision would introduce errors in smart contract inputs, gas calculations, or financial displays. Prefer it over manual multiplication when the value is a very large integer or a high-precision decimal string.
Side effects
- Missing required 'value' query parameter returns an error
- Non-numeric or malformed decimal string in 'value' causes a parse error
- Invalid 'from' or 'to' enum value (not one of the seven supported units) returns a bad request
- Very large integers beyond BigInt range may fail depending on server implementation
