The reference amount

Raw clementines in USDA SR Legacy 2018 contain 48.8 mg vitamin C per 100 g. The listed 74 g fruit therefore provides about 36.1 mg. That number describes a reference portion; it is not a guarantee that every clementine has the same edible weight or vitamin concentration. [1]

Read a daily comparison with the correct denominator

For adults aged 19 and older, NIH ODS lists vitamin C RDAs of 90 mg/day for men and 75 mg/day for nonpregnant, nonlactating women. A reference clementine’s approximately 36 mg supplies about 40% or 48% of those amounts, respectively. Age, pregnancy, lactation and smoking change the applicable target. This is a food contribution, not a recommendation to take that amount as a supplement. [1][2]

A hypothetical two-fruit snack

Two clementines matching the 74 g reference portions total 148 g and provide about 72.2 mg vitamin C. If the combined edible portion instead weighs 120 g, the estimate is 58.6 mg. Counting two fruits is convenient, but the measured edible amount is the more precise input. [1]
