Why weights can differ

Cup measures are not exact. How you scoop, pack or sift peanut butter changes the weight, and brands vary slightly. These figures use a standard US cup of 236.6 ml and common reference values, so treat them as close estimates. For baking, a kitchen scale gives the most reliable result.
