BMI Calculator

BMI is calculated by dividing weight (in kg) by height squared (in m). For example, if a person weighs 70 kg and is 1.75 m tall, their BMI would be: 70 / (1.75 x 1.75) = 22.86 kg/m².

There isn't a single ideal weight for each height, as weight also depends on other factors like age, gender, body composition, and level of physical activity. However, you can use BMI as a reference to determine if your weight falls within a healthy range. According to the WHO, the normal BMI range for adults is between 18.5 and 24.9 kg/m². To find the corresponding weight range for this BMI at each height, simply multiply height squared by the minimum and maximum BMI values. For instance, for a person who is 1.75 m tall, the normal weight range would be: (1.75 x 1.75) x 18.5 = 56.77 kg and (1.75 x 1.75) x 24.9 = 76.31 kg.

If your BMI is below 18.5 kg/m², it may indicate that you're underweight, which can pose risks to your health such as anemia, osteoporosis, infections, and weakness. In this case, it's important to consult a doctor or nutritionist to investigate the possible causes of weight loss and receive guidance on how to increase calorie and nutrient intake in a healthy way.

If your BMI is above 24.9 kg/m², it may indicate that you're overweight or obese, which can also pose health risks like diabetes, hypertension, high cholesterol, cardiovascular diseases, and joint issues. In this case, it's important to consult a doctor or nutritionist to receive guidance on how to reduce calorie and fat intake and gradually increase physical activity in a safe and sustainable manner.
