Understanding Health Metrics
Body Mass Index (BMI)
BMI is a screening tool that uses height and weight to estimate body fat. While useful for population studies, BMI has limitations for individuals, especially athletes with high muscle mass. Our BMI calculator provides additional metrics like body fat percentage and lean mass estimates for a more complete picture. The WHO classifies BMI ranges as: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (≥30).
Calorie Requirements
Daily calorie needs vary based on age, sex, weight, height, and activity level. Our calorie calculator uses the Mifflin-St Jeor equation, considered the most accurate for determining Basal Metabolic Rate (BMR). We then apply activity multipliers to calculate Total Daily Energy Expenditure (TDEE). For weight loss, a 500-calorie daily deficit typically results in 1 pound lost per week.
Pregnancy Tracking
Pregnancy calculators help expectant parents track important milestones. Our calculator determines due date using Naegele's Rule (adding 280 days to the first day of last menstrual period). It also estimates conception date, current gestational age, and upcoming developmental milestones. Remember that only 5% of babies are born on their due date, with most arriving within two weeks before or after.
Medicine Dosage Safety
Proper medication dosing is crucial for safety and effectiveness. Our dosage calculator helps determine appropriate doses based on weight and age, particularly important for children's medications. Always verify calculations with product labels and consult healthcare providers for prescription medications or if you have any concerns.

Health Tracking Best Practices
- Consistency is Key: Take measurements at the same time of day, preferably in the morning before eating.
- Track Trends, Not Daily Fluctuations: Focus on weekly or monthly averages rather than day-to-day changes.
- Use Multiple Metrics: Don't rely on a single measurement. Combine BMI with waist circumference, body fat percentage, and how you feel.
- Set Realistic Goals: Sustainable weight loss is 1-2 pounds per week. Extreme changes are rarely maintainable.
- Document Context: Note factors like illness, stress, or lifestyle changes that might affect your metrics.
