BMI = 85 ÷ (1.75 × 1.75) = 27.8
Imperial System Examples
BMI = (140 ÷ 67²) × 703 = 21.9
BMI = (180 ÷ 64²) × 703 = 30.9
Frequently Asked Questions
What is a good BMI score?
A BMI between 18.5 and 24.9 is considered normal or healthy weight for most adults. However, the ideal BMI can vary based on individual factors like age, muscle mass, and overall health.
Is BMI accurate for everyone?
BMI is a useful screening tool for most people, but it has limitations. It may not be accurate for athletes, elderly individuals, pregnant women, or people with certain medical conditions. It also doesn't account for muscle mass or fat distribution.
How often should I calculate my BMI?
You can check your BMI monthly or whenever you notice significant weight changes. However, focus on long-term trends rather than daily fluctuations, as weight can vary due to many factors.
What should I do if my BMI is outside the normal range?
If your BMI is outside the normal range, consider consulting with a healthcare provider or registered dietitian. They can provide personalized advice based on your overall health, medical history, and individual circumstances.
Can children use this BMI calculator?
This calculator is designed for adults (ages 18+). Children and teens have different BMI standards that account for age and gender-specific growth patterns. Use pediatric BMI calculators for anyone under 18.
Is BMI the only measure of health?
No, BMI is just one indicator. Other important factors include waist circumference, body composition, blood pressure, cholesterol levels, physical fitness, and overall lifestyle. A comprehensive health assessment requires multiple measurements.
