When converting between measurement standards, what is a common conversion factor for mV SCE to mV CAS?

The conversion factor for mV SCE (Saturated Calomel Electrode) to mV CAS (Copper/Copper Sulfate Electrode) is commonly recognized as 1.2. This means that if you have a reading in millivolts from a saturated calomel electrode, you can convert it to the corresponding reading in millivolts for a copper/copper sulfate standard by multiplying by this factor.

Understanding this conversion is critical for those involved in corrosion measurement and control because different electrodes have different reference potentials, which need to be standardized for accurate readings. The appropriate use of this conversion factor ensures that readings taken with one type of reference electrode can be accurately interpreted in the context of another standard. Properly applying this factor is essential for making confident comparisons and decisions based on electrode potential measurements in various applications related to corrosion testing and material assessments.
