Some sample rH (relative hydrogen) scores calculated from ORP and pH, all using the rather universally-accepted formula:

rH = ((ORP + 200) / 30) + (2 * pH)

which is presented on the page on this site at:

which is entitled:

Notes on rH scale:

The rH scale runs from 0 to 42; 28 is mid-point (balance), below 28 is reducing, above 28 oxidizing.   An rH of 42 indicates 1 atmosphere (1 ATM) of partial pressure of O and a –42 exponent partial pressure of H, while an rH of zero (0) indicates 1 ATM partial pressure of H (adjusted for skewing effects of the H+ [aka “acid”] ion) and a –42 exponent partial pressure of O.  Therefore, an rH score of 0 would indicate maximum possible reducing (antioxidant) power, while a score of 42 would indicate the maximum possible oxidizing environment.

So, rH yields a hydrogen proton-unbiased measure of absolute reducing potential of a substance; eliminating effects due to pH.  rH is log1/hydrogen parital pressure; a one unit change in rH indicates a
10X change. E.g., a shift on the Barr scale of rH from a score of 27 to one of 26 indicates a 10X increase in reducing power.  rH 28 = H partial pressure (pp) of 10^-28 atmospheres, an rH 11 = H pp is 10^-11 atmospheres, and a 0 rH is the rH value of pure hydrogen at STP.  Again, as noted above, an rH score of 0 would indicate maximum possible reducing (aka “antioxidant”) power, while a score of 42 would indicate the maximum possible oxidizing environment.
