Protein Calculator
Daily protein grams from body weight and a multiplier you can see. It does not estimate calories. An estimate, not a diagnosis.
Smart Tips
• The result is body weight in kilograms times the multiplier on the menu.
• 0.8 g/kg is the adult RDA. 70 kg at 0.8 g/kg is 56 g, the adult male gram row on the DRI table.
• 1.4 and 2.0 g/kg are the ends of the ISSN range for most exercising people. The page does not call either one an optimum.
• A custom multiplier is shown on the result. Above 2.0 g/kg is labeled as above that ISSN range.
• Pounds convert at 0.45359237 kg per pound.
• For a calorie split instead of body weight, use the macro calculator. This page does not estimate TDEE.

Key Insights
The multiplier is visible
0.8, 1.4, and 2.0 are written on the menu. A custom number is printed on the result. Nothing is hidden in the arithmetic.
Not a calorie rerun
There is no Mifflin–St Jeor form here. If you want grams from a calorie split, use the macro calculator.
ISSN is a range
1.4 to 2.0 g/kg/day is the range the ISSN position stand calls sufficient for most exercising people. This page does not invent a higher optimum.
RDA is the 0.8 line
The adult RDA is 0.8 g/kg. The DRI table’s 56 g row for men matches 70 kg at that multiplier.
Medical Disclaimer
Estimate only: This page is an estimate, not a diagnosis, a lab test, or a treatment plan.
Not medical nutrition therapy: Kidney disease and pregnancy need a clinician. Do not treat the top of the ISSN range as a target for those conditions.
