What’s your number?Adults with a healthy body weight can meet the RDA for protein by consuming 0.8 grams of protein per kilogram of body weight. The calculation is simple. Divide your current body weight in pounds by 2.2 to convert to kilograms, and then multiply that number by 0.8.
Do the math
If weight in pounds is 170: 170/2.2 = 77.3 kg
77.3 kg × 0.8 = 61.84 grams of protein per day
See Appendix 1 for a listing of Recommended Dietary Allowances for protein for all age groups.
