What is an exameter used for?

An exameter is used to express extremely large distances, commonly in astrophysics and cosmology, such as between stars or galaxy-scale separations.

How many meters are in one exameter?

One exameter equals 1,000,000,000,000,000,000 (10^18) meters.

Can exameters be used for everyday measurements?

No, exameters are impractical for everyday use and are intended for ultra-large distance scales.
