Mpc/h

Symbol

 * 1)  An indeterminate unit of distance between 4/3 Mpc and 2 Mpc. The h is a parameter in the closed interval [0.5, 0.75] and reflects an uncertainty in the Hubble constant. For example, in a universe where the Hubble constant is $$70\,\frac{\text{km}}{\text{s Mpc}}$$, h is 0.7. Similarly, a Hubble constant of $$50\,\frac{\text{km}}{\text{s Mpc}}$$ would lead to a value for h of 0.5.
