Our BMI calculator uses the standard BMI formula (weight in kg / height in m²) endorsed by WHO and CDC. It provides accurate body mass index calculations and health status classifications (underweight, normal, overweight, obese). While BMI is a useful screening tool, it doesn't account for muscle mass, bone density, or body composition. Consult healthcare professionals for comprehensive health assessment.

The age calculator determines your exact age by calculating the difference between your birth date and current date (or any specified date). It shows age in years, months, days, hours, minutes, and seconds. Perfect for knowing exact age for forms, celebrating milestones, or calculating age differences. Accounts for leap years and varying month lengths for precision.

Our date calculator helps you: 1) Find days, weeks, months, and years between two dates, 2) Add or subtract days/weeks/months from a date, 3) Calculate business days excluding weekends, 4) Find date differences for project planning, age calculation, or event countdowns. Useful for deadline tracking, pregnancy due dates, retirement planning, and anniversary calculations.

The unit converter supports multiple categories: Length (meters, feet, inches, kilometers, miles), Weight (kilograms, pounds, ounces, grams), Volume (liters, gallons, milliliters, cups), Area (square meters, acres, hectares), Speed (km/h, mph, m/s), and more. Converts between metric and imperial systems instantly with high precision. Essential for cooking, construction, travel, and scientific calculations.

Our loan calculator computes monthly payments, total interest, and amortization schedules for mortgages, auto loans, personal loans, and student loans. Input loan amount, interest rate, and term to see: monthly payment breakdown, total interest paid over loan term, principal vs interest distribution, and payoff timeline. Helps compare loan options, plan budgets, and understand long-term financial commitments.
