BMI Calculator
Your Body Mass Index (BMI) is one of the most widely used screening tools to understand whether your weight falls within a healthy range for your height. While BMI is not a perfect measure of body fat or overall health, it gives you a useful starting point for a conversation with your doctor.
Our BMI calculator is fast, free, and works for both metric and imperial measurements. It also gives you context for your result so you understand what the number actually means.
Pregnancy Due Date Calculator
Figuring out your due date is one of the first things expectant parents want to know. Our pregnancy due date calculator uses the standard clinical method based on your last menstrual period (LMP) to estimate when your baby is likely to arrive.
Keep in mind that due dates are estimates. Only about 5 percent of babies are born on their exact due date, but knowing your expected date helps you and your healthcare provider track your pregnancy milestones.

About Our Calculators
All of our health tools are built on established clinical formulas and guidelines from organizations like the CDC, WHO, and leading medical institutions. They are designed to be educational and give you a useful reference point.
That said, these calculators are not a substitute for professional medical advice. Always discuss your health numbers with a licensed healthcare provider who knows your full medical history.
We will be adding more tools over time. If there is a specific health calculator you would find useful, let us know.
