Instead of working with the Hubble parameter, a common practice is to introduce the dimensionless Hubble parameter, usually noted h, and to write the Hubble's parameter H0 as being H0 = 100 h km·s−1·Mpc−1, all the uncertainty relative of the value of H0 being then relegated on h.[1] Note that other conventions may be found in the literature.
