Enter body weight and a protein intake factor (grams per lb or grams per kg) to estimate protein intake. This calculator can also solve for any one variable when the other two are known.
Quick reference: For generally healthy adults, the RDA is 0.8 g/kg/day (≈0.36 g/lb/day). Higher targets may be used for specific goals and situations (e.g., training, aging, fat-loss phases), but needs vary by age, activity, goals, pregnancy, and medical conditions. For official guidance, check national dietary guidelines and Dietary Reference Intakes, or consult a registered dietitian.
Disclaimer: Educational estimate only; not medical advice. If you have kidney disease/impairment, are pregnant, under 18, older/frail, or have other medical conditions or protein restrictions, consult a clinician or registered dietitian for a personalized target.

Pounds To Protein Formula
The following formula could be used to estimate protein intake based on body weight and an intake factor.
PI = BW * r
Variables:
- PI is the protein intake (grams)
- BW is the body weight (pounds)
- r is the protein intake factor per pound of body weight (grams/pound)
To calculate the protein intake, multiply the body weight by the protein intake factor per pound of body weight. The result is an estimated daily protein intake in grams for the chosen factor.
| g/kg | g/lb |
|---|---|
| 0.5 | 0.227 |
| 0.6 | 0.272 |
| 0.7 | 0.318 |
| 0.8 | 0.363 |
| 0.9 | 0.408 |
| 1.0 | 0.454 |
| 1.1 | 0.499 |
| 1.2 | 0.544 |
| 1.3 | 0.590 |
| 1.4 | 0.635 |
| 1.5 | 0.680 |
| 1.6 | 0.726 |
| 1.7 | 0.771 |
| 1.8 | 0.816 |
| 1.9 | 0.862 |
| 2.0 | 0.907 |
| 2.2 | 0.998 |
| 2.4 | 1.089 |
| 2.6 | 1.179 |
| 3.0 | 1.361 |
| Conversion: g/lb = g/kg ÷ 2.20462 (≈ g/kg × 0.453592). Example reference: 0.8 g/kg/day (RDA for generally healthy adults) ≈ 0.36 g/lb/day. | |
What is Pounds To Protein?
Pounds To Protein is not a recognized term in nutrition, fitness, or weight management. It could potentially refer to a method of calculating protein intake based on body weight, as some fitness and nutrition plans recommend a certain amount of protein per pound of body weight. However, without specific context, it’s difficult to provide a precise definition. It’s always recommended to consult with a healthcare professional or a dietitian for personalized advice on protein intake.
How to Calculate Pounds To Protein?
The following steps outline how to calculate the Pounds To Protein using the formula: PI = BW * r.
- First, determine the body weight (BW) in pounds.
- Next, determine the protein intake factor per pound of body weight (r) in grams/pound.
- Next, gather the formula from above = PI = BW * r.
- Finally, calculate the estimated protein intake (PI).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
body weight (BW) in pounds = 150
example protein intake factor per pound (r) in grams/pound = 0.36 (≈ 0.8 g/kg/day general adult RDA equivalent)
