Health & Fitness Calculators
Health, fitness, pregnancy, and nutrition calculators for wellness tracking
BMI Calculator
Calculate Body Mass Index (BMI) from height and weight in kg/lbs and cm/feet. Check if you are underweight, normal, overweight, or obese with WHO standards and health risk assessment.
Period Calculator
Calculate next period date, cycle length, and menstrual calendar. Predict menstruation, ovulation, and PMS symptoms with accurate period tracking and fertility windows.
Ovulation Calculator
Calculate ovulation day, fertile window, and best days to conceive. Track menstrual cycle and predict fertility period for pregnancy planning with personalized calendar.
Calorie Calculator
Calculate daily calorie needs for weight loss, maintenance, or muscle gain. Estimate TDEE based on age, gender, weight, height, and activity level with personalized nutrition goals.
Due Date Calculator
Calculate baby due date from last menstrual period (LMP), conception date, or IVF transfer date. Track pregnancy weeks, trimester dates, and estimated delivery timeline.
Pregnancy Calculator
Calculate pregnancy due date, conception date, and week-by-week milestones. Track trimester progress, fetal development, and estimated delivery date from LMP or ultrasound.
BMR Calculator
Calculate Basal Metabolic Rate (BMR) - calories your body burns at rest. Use Mifflin-St Jeor or Harris-Benedict formula based on age, gender, weight, and height for metabolism estimation.
Body Fat Calculator
Calculate body fat percentage using US Navy method, skinfold measurements, or BMI formula. Assess fat mass, lean mass, and body composition for fitness and health tracking.
Calorie Burned Calculator
Calculate calories burned during exercise, running, walking, cycling, and daily activities. Track energy expenditure by duration, intensity, and body weight for fitness goals.
Ideal Weight Calculator
Calculate ideal body weight based on height, age, gender, and body frame. Compare Devine, Robinson, Miller, and Hamwi formulas for target weight and healthy weight range.
TDEE Calculator
Calculate Total Daily Energy Expenditure (TDEE) including BMR and activity level. Determine calorie needs for weight loss, maintenance, or muscle building with precise macros.
Conception Calculator
Calculate conception date from due date, birth date, or LMP. Estimate when baby was conceived and determine conception window for pregnancy planning.
BAC Calculator
Calculate Blood Alcohol Content (BAC) level based on drinks consumed, weight, gender, and time. Estimate intoxication level and time to sober up for responsible drinking.
Macro Calculator
Calculate macronutrient ratio (protein, carbs, fats) for diet goals. Get personalized macro split for weight loss, muscle gain, or maintenance with calorie and gram breakdown.
Water Intake Calculator
Calculate daily water intake recommendations based on weight, activity level, climate, and health status. Stay hydrated with personalized fluid requirements in liters or ounces.
One Rep Max Calculator
Calculate one rep max (1RM) for weightlifting exercises. Estimate maximum strength, training percentages, and progressive overload using Brzycki, Epley, or Lombardi formulas.
Protein Calculator
Calculate daily protein requirements for muscle building, weight loss, or maintenance. Get personalized protein intake in grams based on body weight, activity level, and fitness goals.
Target Heart Rate Calculator
Calculate target heart rate zones for cardio exercise based on age and resting heart rate. Optimize fat burn, aerobic, and anaerobic training zones with Karvonen formula.
Pregnancy Weight Gain Calculator
Calculate healthy pregnancy weight gain by trimester based on pre-pregnancy BMI. Track recommended weight gain range for single and multiple pregnancies.
Healthy Body Weight Calculator
Calculate healthy weight range for your height, age, and gender. Determine ideal weight using WHO BMI standards and multiple scientific formulas for optimal health.
Carbohydrate Calculator
Calculate daily carbohydrate needs for energy, weight loss, or athletic performance. Determine optimal carb intake in grams and percentage for low-carb, balanced, or high-carb diets.
Body Surface Area Calculator
Calculate body surface area (BSA) for medical dosing using Mosteller, DuBois, or Haycock formula. Essential for chemotherapy, drug dosing, and medical calculations.
Workout Timer
HIIT interval timer for Tabata, circuit training, and custom workout intervals. Set work/rest periods, rounds, and cooldowns with audio alerts for effective training sessions.
Lean Body Mass Calculator
Calculate lean body mass (LBM), fat mass, and body composition from weight and body fat percentage. Track muscle mass for fitness and nutrition planning.
Fat Intake Calculator
Calculate daily healthy fat intake for optimal nutrition. Determine fat requirements in grams and calories based on diet type, activity level, and health goals.
