Tool Introduction

"Weight Assistant" is a simple and practical online tool designed to help you easily manage your personal weight and monitor your physical health. By entering your height and weight, the tool can instantly calculate your Body Mass Index (BMI) and determine your weight status (e.g., underweight, normal, overweight, or obese) according to internationally accepted standards. We also provide a historical record function (registration/login required), allowing you to track weight changes over time and better plan a healthy life.

How to Use

In the designated input fields, accurately fill in your height (cm) and current weight (kg).
Click the "Calculate BMI" or "Add Record" button.
The tool will immediately display your BMI value and the corresponding weight status assessment.
If you have registered and logged in, your weight records will be automatically saved, and you can view detailed data and trend charts on the "History Records" page.

Frequently Asked Questions

Q: What does the BMI value mean?
A: BMI is the Body Mass Index, used to assess whether your weight is proportionate to your height, thereby determining if your weight is healthy. It helps you get an initial understanding of the risk of obesity or underweight.
Q: What units does the tool support for input?
A: Currently, it mainly supports metric units, i.e., height in "centimeters" and weight in "kilograms".
Q: Can I use Weight Assistant to track my weight changes?
A: Yes, after registering and logging in, you can save each weight record and view historical data and weight change trend charts for long-term management.
Q: My BMI is within the normal range, does that mean I am completely healthy?
A: BMI is an important reference indicator, but it cannot fully reflect body composition (such as muscle mass and fat mass). For professional athletes, pregnant women, children, and frail elderly individuals, BMI assessment results may need to be combined with other health indicators for comprehensive judgment.

Notes

Please ensure that the height and weight data you enter are accurate; incorrect input will lead to inaccurate BMI results.
BMI is a preliminary indicator for health assessment and should not be used as the sole basis for diagnosis. If you have health concerns, please consult a professional doctor.
It is recommended to regularly measure and record your weight; continuous monitoring helps you better understand your health status.
For specific populations, such as minors, pregnant women, professional athletes, etc., BMI standards may vary, please refer to them as appropriate.
