pH itself is not measured in any units, but the units of concentration for the amount free hydrogen ions is in moles per liter of solution. Mol/liter is sometimes just represented by an M, so 10^-3 mol/L looks like 10^-3 M.

Why is a pH scale called a pH scale?

The pH scale is a scale to express the acidity of aqueous solutions (i.e. anything dissolved in water). The scale is divided in equi-distantial units with decimals, comparable with temperature or pressure scales. Commonly it goes from 0 - 14, with 7 being neutral. pH stands for parts of hydrogen. It is the negative log of the hydrogen ion concentration.
