Your BMI of 46.2 puts you in the Obese Class III category for someone 6'1".

Keep in mind that BMI does not account for muscle mass. Two people at 6'1" and 350 lbs can have very different body compositions. Body fat percentage is a more precise indicator of health risk.
BMI is a useful screening tool but has real limitations. It does not distinguish between muscle and fat, so muscular athletes often show elevated BMI despite low body fat. It also does not account for where fat is stored. Waist-to-height ratio and body fat percentage are more precise measures. Use BMI as a starting point, not a definitive health verdict.
For someone 6'1", the healthy weight range based on BMI is 140 to 189 lbs. At 140 lbs, BMI is 18.5 (lower boundary of healthy). At 189 lbs, BMI is 24.9 (upper boundary of healthy). Below 140 lbs is underweight; above 189 lbs is overweight.
BMI only uses height and weight. Body fat percentage measures actual fat tissue as a proportion of total weight, making it more precise for body composition assessment. Two people with the same BMI of 46.2 can have very different body fat percentages depending on muscle mass. Athletes often have BMI values above 25 while maintaining low body fat. Use body fat percentage to set specific fitness goals.
A BMI of 46.2 at 6'1" places you in the Obese Class III category. BMI (Body Mass Index) is calculated by dividing weight in pounds by height in inches squared, then multiplying by 703. The healthy range is 18.5 to 24.9, which translates to 140 to 189 lbs for someone 6'1".
