The BMI Calculator is a health and fitness tool that helps you determine your Body Mass Index (BMI) using your height and weight. BMI is a widely used measurement to assess whether a person is underweight, normal weight, overweight, or obese. With our free online BMI calculator, you can quickly check your BMI and better understand your health status. Our calculator allows you to enter weight in kilograms, pounds, or stones, and height in centimeters, meters, feet, or inches. It provides instant results and displays them alongside a BMI chart for easy interpretation. For example, a BMI below 18.5 means underweight, 18.5–24.9 is normal, 25–29.9 is overweight, and 30 or above indicates obesity. The Body Mass Index calculator is useful for individuals monitoring weight loss, healthcare professionals tracking patients, and fitness enthusiasts working towards specific health goals. However, while BMI is a good general guide, it does not account for muscle mass, bone density, or body composition. Always consult a doctor or nutritionist for personalized advice. Our BMI calculator online is mobile-friendly, fast, and accurate, helping you take control of your health at any time.
