If you wanted to measure a cell, it would be something (not enen close, just example) like this

4.253246 X 10^-43

You are right about not being close. Your number is about 10 quadrillion times smaller than an electron when the unit distance is a light-year.  Electron width in light-years =1.057e-31 Lys

 

Planck length is the smallest measurement of length with any meaning. Aprox.  equal to 1.6 x 10-35 m
