The ATELL (エーテル, Ēteru) is the standard unit for the measurement of ether.
It is defined as "the amount of ether a person creates within one second", and is 1/3600 of a haiki.
ATELL is most widely used to measure the usage of ether in a variety of uses, especially in the usage of ether in abilities. For abilities which use more than 3600 ATELL, haiki is often preferred over ATELL.
- 1 ATELL = 2.78 × 10-4 haiki
