A good way to assess your weight is to calculate your body mass index (BMI). BMI takes into account not just your weight, but also your height to indicate body fat. The goal for most people: a BMI that's over 18 and under 25.
Following are two BMI calculators. One uses imperial units, pounds (lbs), feet (ft) and inches (in). The second uses metric units, kilogram (kilos) and centimeters.
Simply click on the empty boxes for Weight and Height and then click the "Calculat BMI" button to display your BMI. Click on the "Reset!" button to clear all information and to do a new calculation.
About the BMI Calculator
A good way to determine if your weight is healthy for your height is to calculate your body mass index (BMI). Being overweight puts strain on your heart and can lead to serious health problems. These problems include:
Your BMI estimates how much you should weigh, based on your height.

BMI is not always an accurate way to determine whether you need to lose weight. Here are some exceptions:
Body builders: Because muscle weighs more than fat, people who are unusually muscular may have a high BMI.
Elderly: In the elderly it is often better to have a BMI between 25 and 27, rather than under 25. If you are older than 65, for example, a slightly higher BMI may help protect you from osteoporosis.
Children: While an alarming number of children are obese, do not use this BMI calculator for evaluating a child. Talk to your pediatrician about the appropriate weight for your child's age.
In addition, a lot of other factors influence your health. These include:
Your BMI alone cannot predict your health risk, but most experts say that a BMI greater than 30 (obesity) is unhealthy. No matter what your BMI is, exercise can help reduce your risk of heart disease and diabetes. Remember to always ask your doctor before starting an exercise program.
