How can I convert from Gwei to Wei or Ether using web3py

Question

I know there is web3.fromWei('myamount','ether') to convert from Wei to Ether.

But what if I have only the Gwei amount?

Answer 1

You can do:

from decimal import Decimal
def covert(amount):
    #: Convert gwei to wei
    wei_amount = Decimal(amount) * (Decimal(10) ** 9)  # Gigaweis are billions
    eth_amount = web3.fromWei(wei_amount,'ether')
    return wei_amount, eth_amount

Answer 2

If you don't mind importing another library, Brownie's Wei class makes it very simple to get from gwei to wei:

>>> from brownie import Wei
>>> Wei("1 gwei")
1000000000
