What this tool does
This smart BMI calculator helps you calculate BMI instantly and understand what the number means. Besides a BMI category, it shows a healthy weight range, personalized gain/loss target, and practical tips to improve your health. You can switch between metric and imperial units and track your results over time.
How to use
- Choose metric (kg/cm) or imperial (lb/ft/in) mode.
- Enter your weight and height to calculate BMI in real time.
- Review your category, healthy weight range, and how much to gain or lose to reach normal BMI.
- Optional: add age, sex, and activity to get a calorie estimate.
- Track recent BMI results and share your summary if needed.
Example
For 70 kg and 175 cm, BMI is 22.9 (normal range). Healthy weight is about 56.7 to 76.2 kg, so this profile is already in the healthy BMI zone.
FAQ
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered a healthy range.
How can I calculate BMI with imperial units?
Use the imperial mode and enter pounds, feet, and inches. The calculator converts your values automatically and shows the same BMI result.
Is BMI accurate for athletes?
BMI can overestimate body fat for muscular people and may not reflect body composition perfectly. Use it as a screening tool, not a diagnosis.
Does this tool show ideal weight range?
Yes. It calculates your healthy weight range based on BMI 18.5 to 24.9 and shows how much weight to gain or lose to reach that range.
