Children's BMI Calculator
BMI, or body mass index, uses weight and height to calculate weight status for adults. BMI for children and teens also takes into account gender and age because healthy body fatness differs between boys and girls and changes as they grow. This BMI calculator will help you determine if your child is at a healthy weight.

Target Heart Rate Calculator
Your target heart rate is the range at which sustained physical activity - running, cycling, swimming laps, or any other aerobic exercise - is considered safe and effective.
