Protein Calculator

Estimate a reference range or calculate a target using grams per kilogram of body weight.

Your Inputs

Reference for exercising adults: 1.4–2.0 g/kg/day (ISSN, 2017). A range is not a selected target.

How This Calculation Works

Convert pounds to kilograms using 0.45359237, then multiply weight by your selected grams per kilogram.

Example

80 kg × 1.8 g/kg = 144 g/day. The reference range gives 112–160 g/day for 80 kg; it does not select the midpoint for you.

ISSN position stand: protein and exercise (2017)

Limitations

These tools calculate estimates or numerical allocations, not individualized nutrition advice. They do not assess medical needs or food quality. Pregnancy, breastfeeding, medical conditions and children need individual professional guidance.
