Calculators
Calculate Body Mass Index (BMI) using metric (kg/m) or imperial (lb/in) units. Shows BMI category, healthy weight range for your height, and a visual scale.
Follow these simple steps to get instant, accurate results directly in your browser:
Select Metric (kg, cm) or Imperial (lbs, ft/in).
Input your current weight and standing height.
Inspect your calculated BMI score, WHO weight category, and healthy weight range.
The BMI Calculator (Body Mass Index) evaluates body weight relative to height according to standardized World Health Organization (WHO) and CDC weight status classifications (underweight, normal weight, overweight, obesity).
Body Mass Index is an inexpensive, non-invasive screening tool used by clinicians, epidemiologists, and fitness professionals worldwide to evaluate weight categories that may lead to health complications. The calculator supports both metric units (kilograms and centimeters/meters) and imperial units (pounds, feet, and inches).
Medical Disclaimer: BMI is a screening metric that does not directly measure body fat percentage or distinguish between muscle mass and fat tissue. Calculations run locally in your browser memory without server transmission.
Disclaimer: This tool provides general estimates for informational purposes only and does not constitute medical advice. Consult a healthcare professional before making health or fitness decisions.
Metric: BMI = weight (kg) / [height (m)]^2 | Imperial: BMI = [weight (lbs) * 703] / [height (in)]^2Calculates weight in kilograms divided by the square of height in meters.
Height = 180 cm (1.80 m) | Weight = 75 kg Height Squared = 1.80 * 1.80 = 3.24 m^2 BMI = 75 / 3.24 = 23.15 kg/m^2 Classification: Normal Weight (Healthy range 18.5 - 24.9).
Our calculation methodologies adhere to published guidelines from authoritative government agencies and standards bodies:
Classifies scores into Underweight (<18.5), Normal (18.5–24.9), Overweight (25–29.9), and Obese (>=30).
Seamlessly switch between kilograms/centimeters and pounds/feet/inches.
Displays the exact minimum and maximum healthy weights for your specific height.
Your weight and height metrics are never uploaded to any server or tracker.
Check where your weight falls on standardized clinical weight charts.
Calculate your healthy target weight range (BMI 18.5–24.9) before beginning fitness programs.
Determine baseline BMI figures required for health assessments and physicals.
