Nutrition & Diet
Blood Alcohol Level Safety Check
Use this only for harm-reduction education. Enter standard drinks, body weight, sex, and elapsed time to see an estimated BAC and a clear reminder not to drive after drinking.
Body Surface Area Calculator
Estimate body surface area from height and weight, compare Mosteller and Du Bois results, and keep the value in the correct clinical context.
Body Type Calculator
Calculate body type classification from Height, Weight, Wrist and ankle measurements, with the key formulas and caveats needed to interpret the result correctly.
Carbohydrate Calculator
Choose a calorie target and diet style to estimate a daily carbohydrate range in grams, then compare it with your protein and fat targets.
Fat Intake Calculator
Enter daily calories and a diet style to estimate total fat grams plus the saturated-fat ceiling implied by your calorie target.
GFR Calculator
Estimate eGFR from creatinine, age, and sex with the 2021 CKD-EPI equation, then read the result as a screening estimate rather than a diagnosis.
Macro Calculator
Choose a calorie target and macro split to convert protein, carbohydrate, and fat percentages into grams. Use the result as a meal-planning framework, not as a personalized nutrition prescription.
Protein Calculator
Enter body weight, activity level, and goal to see your daily protein target in grams. Compare the DRI minimum against evidence-based sports nutrition ranges — and understand why protein needs differ so dramatically by goal and training status.
TDEE Calculator
Enter your age, sex, weight, height, and activity level to see your Total Daily Energy Expenditure — the calories you actually burn each day. Compare activity levels side by side to see exactly how much your daily routine shifts your calorie budget before you build a plan around it.
