The yoctometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: ym) or yoctometer (American spelling) is an SI measure of length that is equal to 1024 (yocto) of a metre. A yoctometre is equivalent to 1/100,000 the diameter of a proton or neutron.[citation needed]

  • 1 ym = 1×1024 metre

In terms of relative length of units, a yoctometre ranks as follows: Planck length << yoctometre << zeptometre. A yoctometre is 1/1000 of a zeptometre (1 zeptometre (zm) = 1,000 yoctometres). The yoctometre,is the distance light travels in about:1÷2.99×1035 seconds.

Measurement Equivalents[edit]

There are some objects in the universe that can easily define yoctometre.They are considered as the smallest objects in the universe.

Quarks[edit]

They are smaller than any particle,composes atoms.They are commonly about a yoctometer and some are zeptometres.

Uses[edit]

It is rarely used.It is commonly a measurement of quarks but used in measuring objects smaller than atom.As the smallest SI unit,yoctometer is used in worldwide scientific measurement and laboratory observations.It is used in measuring sub-atomic particles.
