❓ Frequently Asked Questions (FAQs)
1. What does BMI stand for?
BMI stands for Body Mass Index. It’s a ratio of your weight to your height and is used to estimate body fat.
2. Is this calculator only for men?
Yes, this version is designed specifically for men. It factors in male body composition and age-specific BMI categories.
3. What is a healthy BMI for men?
For most adult men, a healthy BMI ranges from 18.5 to 24.9. However, older men (65+) may have a slightly higher ideal range.
4. Can I use feet and inches instead of centimeters?
Absolutely. Just select “ft/in” in the height unit dropdown and enter both feet and inches.
5. What if I don’t know my body frame?
If unsure, select Medium Frame for a general estimate. For more accuracy, measure your wrist circumference.
6. Is BMI enough to determine my health?
No. BMI is a starting point. This tool also includes body fat %, muscle mass, and calorie needs for a fuller picture.
7. What is BMR?
BMR stands for Basal Metabolic Rate—it’s the number of calories your body burns at rest. This calculator uses it to estimate daily calorie needs.
8. What’s the difference between BMI and body fat percentage?
BMI uses height and weight only, while body fat percentage considers age and gives a more detailed look at body composition.
9. How is muscle mass calculated?
The calculator estimates lean mass by subtracting body fat weight from your total body weight.
10. Can I use this if I’m an athlete?
Yes, but note that muscular individuals may have a high BMI while being healthy. Focus more on body fat % and muscle mass.
11. Is there a version for women?
Yes! A BMI calculator for women is available with gender-specific formulas and ideal ranges.
12. Can I use this daily?
