With most soluble oils the index is 1, so a refractometer reading of 5 multiplied by an index of 1 = 5% concentration. However, many semi-synthetics, synthetics, grinding fluids, and some soluble oils can have a refractive index from 1.5 to 3. So a refractometer reading of 5 multiplied by an index of 1.75 = 8.75% concentration.
