如何使用 BMI计算器

Enter your height and weight, choosing between metric (cm/kg) or imperial (ft-in/lbs) units. The calculator computes your Body Mass Index (BMI) and shows which category you fall into: Underweight (< 18.5), Normal (18.5-24.9), Overweight (25-29.9), or Obese (30+). While BMI is a useful screening tool, it doesn't account for muscle mass, bone density, or body composition.

常见问题

Is BMI accurate for everyone?+
BMI is a general screening tool, not a diagnostic one. It may overestimate body fat in muscular athletes and underestimate it in older adults who have lost muscle mass. Always consult a healthcare provider for a complete assessment.
What is a healthy BMI range?+
The World Health Organization defines a healthy BMI as 18.5 to 24.9. However, optimal ranges can vary by age, sex, and ethnicity.
How is BMI calculated?+
BMI = weight (kg) / height (m)². For imperial units, it's BMI = (weight in lbs × 703) / (height in inches)².
