Frequently Asked Questions
What is a healthy BMI?↓
According to the World Health Organization (WHO), a BMI between 18.5 and 24.9 is considered normal weight. A BMI below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.
How is BMI calculated?↓
BMI is calculated using the formula: BMI = weight (kg) / height (m)². For example, a person who is 70 kg and 1.70 m tall has a BMI of 70 / (1.70 × 1.70) = 24.2. In imperial units, the formula is BMI = (weight in lbs × 703) / height in inches².
What is the BMI for 5'10" and 180 lbs?↓
At 5 feet 10 inches tall (70 inches / 177.8 cm) and 180 lbs (81.6 kg), your BMI is approximately 25.8, which falls in the Overweight category (25–29.9). The healthy weight range for 5'10" is approximately 132–174 lbs (60–79 kg).
Is BMI accurate?↓
BMI is a useful screening tool but has limitations. It does not directly measure body fat, and it cannot distinguish between muscle mass and fat mass. Athletes with high muscle mass may have a high BMI despite being very lean. BMI also does not account for age, sex, or where fat is stored on the body. It should be used alongside other health assessments rather than as a standalone diagnostic measure.
