Files360 BMI Calculator is a quick, free tool for calculating your Body Mass Index — one of the most widely used health screening metrics. BMI provides a simple numerical assessment of whether your weight is proportionate to your height, helping identify potential weight-related health risks.
The calculator uses the internationally recognized WHO formula: BMI = weight (kg) / height (m)². Based on the result, you're categorized as Underweight (BMI < 18.5), Normal weight (BMI 18.5-24.9), Overweight (BMI 25-29.9), or Obese (BMI ≥ 30). Each category has different health implications and guidance.
It's important to understand that BMI is a screening tool, not a diagnostic measure. It doesn't directly measure body fat or account for factors like muscle mass, bone density, age, sex, and ethnicity. Athletes and people with high muscle mass may have elevated BMI without excess body fat. For a comprehensive health assessment, consult a healthcare professional.
The calculator is completely private — your height, weight, and BMI data stay in your browser and are never transmitted to any server. Calculate your BMI as often as you like to track trends over time, with no account, no data collection, and no ads tracking your health preferences.
