Metabolism Calculators

Total Parenteral Nutrition (TPN)

This calculator helps determine the total nutritional needs of patients requiring parenteral (IV) nutrition. It estimates Basal Energy Expenditure (BEE), Ideal Body Weight (IBW), macronutrient distribution (lipids, dextrose, protein), nitrogen balance, and the non-protein calorie-to-nitrogen ratio.

Resting Metabolic Rate (RMR)

This calculator estimates your Resting Metabolic Rate (RMR) — the number of calories your body needs at rest to maintain vital functions like breathing, circulation, and cell production. It's based on weight, height, age, and gender using the Mifflin-St Jeor equation.

Mifflin-St Jeor BMR

This calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor Equation. It provides the number of calories your body needs at rest based on your age, gender, weight, and height—essential for weight management and nutrition planning.

Karvonen Heart Rate

This calculator estimates your target heart rate for exercise using the Karvonen formula. It considers your age, resting heart rate, intensity percentage, and gender to calculate personalized training zones for optimal cardiovascular performance.

Heart Rate Calorie Burn

This calculator estimates how many calories you burn during exercise based on your heart rate, weight, age, duration, and gender. It provides a personalized calculation using scientifically validated formulas for males and females.

Heart Beats Since Birth

This calculator estimates how many times your heart has beaten since you were born. Based on your birth date and average resting heart rate, it provides a fun and fascinating insight into your body's lifelong activity.

Type 2 Diabetes Insulin Level

This calculator estimates insulin level requirements for individuals with Type 2 Diabetes Mellitus. By inputting your weight, height, fasting blood glucose (FBG), and an adjustment factor, it provides a personalized estimate to support diabetic health monitoring.

Bruce Protocol VO₂ Max

This calculator estimates VO₂ max using the Bruce Protocol treadmill stress test. It measures cardiovascular endurance based on exercise duration and provides an approximation of oxygen uptake (mL/kg/min), helping athletes and clinicians evaluate heart and lung fitness.

Breath Counter Since Birth

This fun health calculator estimates how many breaths you have taken since the day you were born. Simply enter your birth date, and the tool will calculate your total number of breaths based on an average respiration rate.

Blood Pressure Range

This calculator helps you assess your blood pressure levels by entering systolic and diastolic values. It determines whether your blood pressure is normal, elevated, or within hypertensive stages, offering a quick and easy way to monitor cardiovascular health.
