pH has no unit because it's a it's a logarithmic scale, not a measurement like grams or degrees.
The pH number directly relates mathematically to the actual concentrations in solution. Concentration itself does have units, but pH really only looks at the power (or exponent) of the concentrations. And, for that reason the unit doesn't carry.
pH = - log [H30+] (mathematical definition)
= negative logarithm of the hydronium ion concentration.
What this means is that if a solution has a concentration of 10-7 M [H30+] or (0.0000001 moles per litre of the hydronium ion), the negative log of this number = 7. Therefore the pH = 7.
But it's not 7 moles per litre or 7 moles or any other transferable unit. It's just 7.
Hope that helps a little.
They are logarithmic. A change of one unit is order of magnitude in difference; that is 10 times as much.
Every unit represent the activity of the ion H+.
pH value(not the 'unit' just the scale)
pH meters are precise to +/- 0.1 to +/- 0.01 pH unit (+/- 6 to +/- 0.6 mV) qith a full-meter scale of 14 pH units (about 840 mV)
The phtwo is another name for the ph scale.

No, the pH scale ranges from 0-14 and is considered a logarithmic scale.
7 is neutral on the pH scale.
