What percentage conversion is used to convert upper extremity rating to whole person?

• A. 0.25
• B. 0.6
• C. 1.0
• D. 0.75

Answer: (B)

In California impairment ratings, the percentage you assign to a body part is not the same as the whole person impairment (WPI). To translate limb-specific impairment to WPI, you apply a conversion multiplier that depends on the body part. For the upper extremity, the standard conversion multiplier is 0.60. So you multiply the upper extremity rating by 0.60 to arrive at the whole person impairment. For example, an upper extremity rating of 40% would convert to a WPI of 24% (40% × 0.60). The other options (0.25, 1.0, 0.75) are not the standard upper-extremity-to-WPI multipliers.
