Pregnancy Conception Calculator
Estimate the probable date of conception and peak fertile ovulation window.
Pregnancy Due Date Calculator
Calculate expected delivery date based on last period, ultrasound, conception, or IVF.
Biometric Standards, Metabolic Formulas & Health Indices
DocketCrop's fitness calculators deploy globally peer-reviewed anthropometric models including the Mifflin-St Jeor equation for Basal Metabolic Rate (BMR), the World Health Organization (WHO) Body Mass Index (BMI) classifications, and the U.S. Navy circumference method for body fat percentage estimation.
Mifflin-St Jeor Metabolic Estimation
Resting metabolic expenditure is estimated via BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + s, where s is +5 for males and -161 for females.
Total Daily Energy Expenditure (TDEE)
Daily maintenance caloric burn applies standard physical activity multipliers (1.2 for sedentary up to 1.9 for extremely active) to establish caloric deficit or surplus targets.
WHO Body Mass Index (BMI) Brackets
Standard metric weight-to-height squared ratios (kg/m²) categorized into Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (30+).
