A yottametre (American spelling: yottameter, symbol: Ym) is a unit of length equal to 1024 metres.
Yottametres could be used for measuring intergalactic distances, but astronomers have been long accustomed to use light-years and parsecs instead.
- 1 Ym is equal to 105700000 light-years or 32408000 parsecs
- diameter of the Local Supercluster is 2 Ym
- distance to the farthest quasars is 100 Ym
- distance to the cosmic light horizon is 130 Ym
