In a similar fashion with how a satoshi is the smallest unit of BTC, an ætto is the smallest unit of AE.
1 AE = 1 ætto x 10^18 = 1000000000000000000 ættos
1 ætto = 0.000000000000000001 AE
Feel free to use the converter tool below to convert from AE to ættos and vice versa.
This tool can come in very handy for those who use the æternity Telegram tipping bot as withdrawals are in the units of ættos.
